“Chin Wong Kee, Discharge Certificate” 1901, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Chin Wong Kee case file, Seattle Box 1396, 41560/24-3.
Chin Wong Kee 陳黃記 was born in Watsonville, California in 1879. He was the son of Chin Din Ling and Wong She. About 1884 he went back to China with his parents and younger brother, Chin Loy Foo, to Bok Wut village. Chin Wong Kee (marriage name Chin Ai Goon) married before he and his brother returned to the United States in 1901. They landed at Vancouver, B.C., travelled to Montreal, then entered the United States at Rouses Point, New York. [south of Montreal]
They were immediately arrested. They were sent by train to jail in Plattsburg, NY. [about 24 miles south of Rouses Point]. They were in jail there for about four months. They received their discharge papers at Port Henry [about 54 miles south of Plattsburg] from Fred W. Dudley, U.S. Commissioner, Northern District of New York in August 1901. Their father’s younger brother, Chin Don Suey, was a witness for the brothers. The discharge papers enabled Chin Wong Kee to obtain his Certificate of Identity #20529.

His adult son, Chin You Dick, was admitted at the Port of Seattle in 1915 and was living and working in Mount Vernon, New York. Chin Wong Kee was working nearby in a restaurant as a waiter. His wife died in China in 1919.

Hazel Ying Lee – Portland Female Aviator

Hazel Ying Lee – Portland Female Aviator
“Lee Yuet/Yut Ying (Hazel) Affidavit photo” 1937, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Lee Yuet Ying (Hazel ) case file, Seattle Box 582, 7030/5149 & Box 710 7030/10411.

[The amazing thing about Hazel Lee’s file is that it does not mention that she was a member of the Chinese Flying Club of Portland and graduated from aviation school at Swan Island, Portland, Oregon in 1932. Hazel Ying Lee was one of the first female pilots in the United States. Her file ends in 1938. After she returned to the United States in 1938 she became one of the first Chinese-American female military pilots. See the links at the end of this article to find out more about her. The blog entry for Virginia Wong tells how the connection was made between Virginia Wong and Hazel Ying Lee, Arthur Chin and the other Chinese-American pilots.]
The file for Hazel Ying Lee (Lee Yut-Ying 李月英) tells us that she left for China on 4 March 1933 and returned on 12 December 1938. While she was visiting her father’s village in the Toyshan District, Kwangtung Province, she received word that her Form 430, Citizen Return Certificate, was destroyed in a fire in Hong Kong. When Lee wanted to return to Portland she went to the U.S. Consulate in Hong Kong for help with her documentation of her U.S. citizenship. They advised her to obtain an affidavit with a current photo swearing to her citizenship.

Hazel Lee’ s brother [the file does not say which brother] went to the Immigration office in Portland to assure that the paper work was in proper order so that Hazel Lee would be admitted when she arrived in the Port of Seattle. The Portland immigration office had a copy of Hazel’s original approved 1933 Form 430 on file. When Hazel arrived in Seattle in 1938 the 1933 information was compared to the new affidavit prepared in Hong Kong and Hazel Lee was admitted to the United States.

Hazel’s 1933 interrogation stated that Hazel attended Atkinson school and High School of Commerce; she was employed at H. Liebes & Company doing stock work and elevator operation; her father, Lee Yet 李乙died in 1930; and her mother was living in Portland. Hazel had nine siblings: Harry Lee, Victor Lee, Howard Lee, Daniel Lee (Lee Wing Doong 李榮宗), Rose Lee, Florence Lee, Gladys Lee, Frances May Lee. Harry and Rose were born in China and the others were born in Portland. Hazel was going to Canton City to visit and study.
Hazel’s mother, Wong Shee, maiden name Wong Seu Lan, was a witness for her. Dr. Jessie M. McGavin, a Caucasian female physician, attended to Wong Shee for Hazel’s birth on 25 August 1912. Her birth certificate is included in the file. The reference sheet in Hazel’s file includes the name, relationship and file number for Hazel’s parents, four brothers and three sisters.

Robert Eugene Lee – Chinese/African American of Philadelphia

Lee Robert Eugene 1916 Aff
“Robert Eugene Lee and Lee Chong, affidavit photos ,” 1916, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Lee Quock Bong (Robert Eugene Lee) case file, Seattle Box 686, 7030/8391.

Robert Eugene Lee (Lee Quock Bong) was born on 24 February 1897 at 208 North 9th Street in Philadelphia. His parents were Lee Chong and Musetta Lee. His father was Chinese and his mother was “a negress.” In 1902 Lee Chong and his family visited his home village, Dong Nom Ho Village, Hok Dan District, China. Mrs. Lee died two months after arriving in China. Lee Chong returned to Philadelphia in 1903 and the children stayed in China with their father’s family.

In 1916 Lee Chong was applying to have his son, Robert Eugene Lee, join him in Philadelphia. He swore in an affidavit that he was a laundryman at 1939 East Sargent Street, in Philadelphia, Pennsylvania; a widower and father of three American-born children, Robert Eugene Lee, aged 18; Mable Luella Lee, age 16, and Gum Len Lee, age 13, who were living in China. His son was married but his wife would be staying in China.

Mary E. Moy, age 45, was a witness for Lee Chong and his son. She testified that her sister and Dr. Bates attended Musetta Lee at Robert’s birth. Mrs. Moy, a Caucasian, was married to a Chinese, Goon Moy. Her husband and Robert’s father, Lee Chong, were close friends.

Other witnesses were Lee Tong, manager of Chong Woh Company in Philadelphia and Agnes A. Ming, a Caucasian who knew Robert’s parents well. She testified that she had known Lee Chong since she was twelve years old and that Lee Chong married Zada Brown, “a colored girl,” who lived over his laundry at 18th and Wharton streets. After their three children were born the Lee family moved to China and Zada died there in 1903. Agnes went to school with Zada, a mulatto. Agnes’ husband was Chinese and a friend of Lee Chong. The Mings lived in Albany, New York.

Lee Chong (American name Joe Lee), (marriage name Lee See Tai), was 49 years old, a laundryman. He received his certificate of identity or residence 107002 in Philadelphia in March 1894. [The file sometimes refers to the certificate as identity and sometime as residence.]
In a letter recommending approval of Robert’s documents, Charles V. Mallet, Chinese and Immigrant Inspector at Gloucester City, New Jersey stated,

“The witnesses Mary Moy and Agnes Ming are both white women
who are or have been married to Chinese, and both of them
convince me of their credibility in connection with their
testimony affecting the applicant; Mrs. Moy being a woman
whose personality should place her way above the status of
one who ordinarily consorts with Chinese. I personally know
something about this witness and have to say for her that
she has raised a family of boys in a manner which should do
credit to any mother. The Chinese witness, Lee Tong, is one
of the most responsible and respected merchant in
Philadelphia Chinatown, and his testimony should be
accorded corresponding weight. The alleged father of the
boy gives the impression of one who is disposed to tell the
truth with his knowledge, and manifests a true parent’s
interest in the applicant…”

In a 1916 statement approving Robert Eugene Lee’s arrival, H. W. Cunningham, Chinese and Immigrant Inspector, Vancouver, B.C. said, “…the claims made are genuine, and in addition applicant’s features plainly indicate an admixture of negro blood. Applicant is admitted and furnished a certificate of identity.”

The file lists the following documents were examined: the baptismal cards for Robert Eugene Lee and Mabel Luella Lee at Philadelphia, 12 December 1901; a 1911 copy of a birth certificate for Chinese female Lee, [Gum Len Lee] born 21 July 1902; and passport 62682 issued 9 October 1902 to Musetta Lee accompanied by her three minor children. [Unfortunately these documents are not included in the file.]

Robert lost his certificate of identity in 1921 but was able to get it replaced.

Robert Eugene Lee made two more trips to China. He was gone from 1922 to 1924. His son, Lee Tong Chee, arrived in the U.S. in 1928. His wife, Chong See, and his other son, Lee You Kue, stayed in China. In 1936 Robert, age 39, applied to visit China and was approved. He returned in June 1937.

The Ancestors of Edwin Mah Lee, recently deceased mayor of San Francisco (1952-2017)

Edwin Mah Lee, (李孟賢) the mayor of San Francisco, died unexpectedly on 12 December 2017. He was born on 5 May 1952 in Seattle, Washington, the son of Gok Suey Lee and Pansy Chin Lee (Chan Ngar Ching).
[See the many tributes to Edwin Mah Lee on the Internet and in newspapers. The following is a brief summary of some of documents in Chinese Exclusion Act case files for his father, grandfather and great grandfather.]

Lee Gok Suey (Edwin Mah Lee’s father)
In August 1937 Lee Ling Hung swore in an affidavit that he was a citizen of the United States and the holder of Certificate of Identity No. 34552 issued when he entered the Port of Seattle on 9 February 1921. He was applying to bring his son, Lee Gok Suey, into the United States.

Lee Gok Suey Lee and Ling Hung AFF 1937
“Affidavit with photos of Lee Gok Suey and Lee Ling Hung,” 1937, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Lee Gok Suey case file, Seattle Box 747, 7030/10684.

Lee Gok Suey arrived in Seattle, Washington on 20 December 1937 on the Princess Marguerite and was admitted four months later after a difficult but successful appeal. He was 17 years old, a student and the son of Lee Ling Hung, a United States citizen and Luey Shee. He was born on 9 May 1921 in Taw Long village, Suey Low Section, Hoy San District, China. Originally Lee Gok Suey was denied admission by a board of special inquiry because he was not able to prove to their satisfaction his relationship to his father.
Seattle’s Inspector-in Charge, Joseph H. Gee, re-opened Lee’s case so additional evidence could be obtained. Affidavits from his father, uncle and grandfather were submitted to the board for their review. The applicant’s attorney filed a letter and an affidavit of the applicant’s alleged grandfather, Lee Share Young, and included a photograph with a satisfactory resemblance to Lee Gok Suey. Because of several discrepancies in the witnesses’ testimony the board voted unanimously that Lee not be admitted. His attorney argued that it had been fifteen years since the grandfather had been to China so it was not unusual that his testimony might not completely agree with his two sons who had been to China recently. After more than four months, Lee Gok Suey’s arrival was approved.

Lee Ling Hung (Lee Gok Suey’s father; Edwin Mah Lee’s grandfather)

Lee Ling Hung CI App 1921
“Certificate of Identity Application, Lee Ling Hung,” 1921, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Lee Hing Hung case file, Seattle Box 433, 7030/719.

Lee Ling Hung first arrived in the United States at Seattle on 21 January 1921 and was admitted as a citizen son of a native. He visited China in 1926 and returned in 1928. During his pre-investigation examination before leaving in 1926 he stated he had one son, Lee Gok Sui, born in 1921. On his return he claimed a second son born while on that trip, Lee Gok Foo. In an application for another trip to China in 1930 he claimed that his second son’s name was Lee Gok Gong and his third son was Lee Gok Foo. Because Lee Ling Hung’s father, Lee Share Young (sometimes spelled Lee Shere Yung)’s citizenship had been granted in 1888 through U. S. District Court discharge papers, Immigrant Inspector Roy M. Porter recommended that Lee Ling Hung’s application for pre-investigation of status be approved. [The confusion over the names of the second and third sons and their dates of birth caused the inspectors to distrust Lee Ling Hung’s testimony and combined with other discrepancies made Lee Gok Suey’s arrival approval so complicated in 1937.]
Before moving to Seattle Lee Ling Hung lived in Portland, Oregon for about six years and he was a baker for Coffman’s Candy Shop at 152 Broadway.

Lee Share Young (Lee Gok Suey’s grandfather; Edwin Mah Lee’s great grandfather)

In March 1938 Lee Share Young (You Yuey, marriage name) testified that he was a bookkeeper at the Quong Tuck Company in Seattle. He was the father of Lee Gim Jeow and Lee Ling Hung and the grandfather of Lee Gok Suey. He was re-examined regarding some of the questions where there was some confusion—were there twelve rows of houses in his village or thirteen? Lee Share Young said, “There are thirteen rows but the first row at the head is not a regular row because there is only a small house and some toilets there.” [It is easy to see how this trivial fact could be confusing.] Lee Share Young’s son sent him a photo of Gok Suey Lee in 1932. The interrogator asked how he could identify his grandson since he had not seen him since he was two years old. He replied, “I have to trust my son who sent me the picture.” There were other discrepancies about the extended family and deceased ancestors, the location of neighbors’ houses in their home village, and the applicant’s school experience. Eventually the board of special inquiry decided that there was enough information where the all the witnesses agreed and they admitted Lee Gok Suey. There were over fifty pages of interrogation. The witnesses were asked about the village, the location of roads, paths, hedges, ponds, shrines, the school, cemetery, stores, and many other minor details. They gave detailed descriptions of the houses, buildings and the people who lived in them. [There were over one hundred houses in their village so this could not have been easy.]

In 1920 Lee Share Young swore in an affidavit that he wanted to bring his son Lee Ling Hung over to the United States. At that time he was a merchant for the Quong Sang Wo Kee Company in Portland, Oregon. He produced his 1888 discharge papers for the interrogators inspection.

When Lee Shere [Share] Yung left for a visit to China in 1900 he obtained an affidavit with his photo attached to assure his reentry into the United States. He swore that he was a member of the Wau Yune Lung Kee Company, dealers in Chinese merchandise and provisions doing business at 739 Commercial Street in San Francisco. He had four witnesses: Chas. E. Harris, O. R. Beal, Frank B. Hoyt and Edgar A. Greenblatt. Lee returned on 2 May 1902.

Lee Share Young, Lee Gok Suey’s grandfather, was born in San Francisco, California on 7 December 1871 to Lee Yeu May and Hong Shee. His marriage name was Lee Yeow You and he was sometimes known as Lee Yung. He married Toy Shee and they had two sons, Lee Gim, born 14 February 1889 and Lee Ling Hung, born 28 November 1901. Lee Share Yung’s paternal grandparents were Lee Sing Tem and Lew Shee. He had an older brother, Lee Seah Fook, living in California. The parents of his wife, Toy Shee, were Toy Lem Tick and Low Shee.

Gee G. Baine (Gee Quock Bin) – law student at Suffolk Law School, Boston

Photo of Gee G. Baine
“Photo of Gee G. Baine from Form 431,“ 1916, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, Gee G. Baine (Gee Quock Bin) case file, Seattle Box RS 285, RS 34,340.

Gee G. Baine was studying law at Suffolk Law School, Boston, Massachusetts in 1916 when he applied for pre-investigation of status so he could visit China.
After a careful investigation Henry M. White, Commissioner of Immigration in Boston approved Gee’s application. White agreed with Inspector McCabe saying that the application “requires a liberal interpretation of the law to approve this application…”

“The applicant was lawfully admitted to the country and so far as developed has maintained an exempt status during the last past year. He thus has met the requirement of rule 15. True, in years gone by, he was a laborer within the meaning of the law, and at times might have been arrested on the charge of being unlawfully with the United States. It is doubted, however, that because of his doings at that time he should now be denied the right to visit his home county.”

Gee G. Baine originally entered the U.S. under the name Gee Quock Bin in San Francisco in June 1896. He lived with his uncle Dr. Gee in New York City, before moving to New Brunswick, New Jersey where he was tutored by a private teacher. He attended several schools over the years: the Thirteenth Street School In New York City, School #11 in Brooklyn, Horace Mann School in Newtonville, Massachusetts; a public school in New York City, and Berkeley Preparatory School in Boston. He was sick with pneumonia one winter then went to Boston where he worked for Mr. Monerly as a chauffeur. When his uncle Dr. Gee returned to China he gave Gee a partnership interest in the Royal Restaurant in Boston. Before Gee was accepted to law school he sometimes worked at the restaurant.

Gleason L. Archer, an attorney, the Dean and founder of the Suffolk Law School in Boston, swore in a statement that Gee Baine had been a student since August 1915 and attended classes three evening a week. He had a good attendance record and good grades having completed courses in contracts, criminal law, torts, agency, legal ethics, and real property. His personal history record showed that his references were Joseph F. O’Connell and Dr. C. H. Thomas of Cambridge.

Edgar S. Monroe, an optometrist in Boston, testified that he had known Gee about twelve years and he had seen him studying law for the last year or two. Monroe did not have personal knowledge that Gee had not worked as a laborer in a restaurant or laundry in the last year but he felt that Gee was worthy and always a gentleman—one that he would not feel ashamed to associate with in any society.

George A. Douglas, an attorney and instructor at Suffolk Law School, attested that he had known Gee since 1915 as a student in his classes in criminal law and agency. Gee attended classes faithfully. Although Douglas could not swear that Gee had not done any manual labor in the last year he knew that his attendance at school and the time needed for studying must have kept Gee extremely busy.
Gee testified that he arrived in 1896 when he was twelve years old and was admitted as a section 6 student. In the past year his only work for the Royal Restaurant was as an interpreter for the business.
In Henry M. White, Commissioner of Immigration’s letter approving Gee’s application he refers to Section 6 Exemption; rule 15 of the Chinese Exclusion Act. See Rule 15 (b)1 below:

Section 6 Exemption; rule 15 (b)
Section 6 Exemption; rule 15 of the Chinese Exclusion Act. See Rule 15 (b)

[The interviewers overlooked the fact that over the years Gee had sometimes found it necessary to work as a laborer. Because he was in the U.S. as a student he could have been deported if this became known to the authorities. The interviewers decided to concentrate on Gee’s previous year. It appeared that he was a full time student and was only associated with the restaurant in a managerial capacity.]
[Although Gee’s application was approved there is no indication in the file that he ever left the country.]

Mable June Lee, a princess for the 1939 Oregon Winter Sports Carnival, was applying to leave Portland to publicize Oregon and Mount Hood in Mexico. She and the royal court traveled to Nogales, Arizona, then spent five days in Mexico City and returned via El Paso, TX. The trip was made by train and would take three weeks.
Mable was 21 years old and born in Portland. She was a checker at the Orange Lantern Tea Room in Portland.
Mable’s brother, Lee Shear Nuey, also known as Louis Lee, was a witness for her. Their parents were both dead and were buried River View Cemetery in Portland. According to C. J. Wise, the examining inspector, Lee spoke English perfectly. Lee did not know much about his grandparents; they had all died in China many years ago. Besides Mable he had two sisters and three brothers: Lee Lin (Mrs. Chin Chow), Lee Tai Hai (died of the flu in Portland in 1919 and buried in the Lone Fir Cemetery), Lee Tommy Shear Gong (born on the boat crossing from China about 1914 on his parents’ one visit to China. He was now living in Stockton, CA), Lee Shear Gum, a chef at Green Mill in Portland and another brother living in Cuba.
Lee Lin, Mable’s older sister, was also a witness for her. Lee Lin was born in San Francisco in 1894. She was married to Chin Chow and they had seven children—two boys and five girls. Her daughter Dorothy Chin Kum was adopted out to Mrs. Sing Ho. She also had a daughter, Ah Me, who died of the flu.
Mable’s file includes a certified copy of her birth certificate and her itinerary for her trip to Mexico City.

“Photo of William Jue Poy,” 1932, Chinese Exclusion Act case files, RG 85, National Archives-Seattle, William Jue Poy (Jue Soo Kuen) case file, Portland, Box 99, 5017/872.

William Jue Poy, Chinese name Jue Soo Kuen, was born at 365 E. 12th Street, Portland, Oregon on 22 May 1904. His parents were Jue Poy and Choy Lain. William Poy attended local schools in Portland, University of Washington in Seattle and Northwestern University in Chicago; did his internship and residency and was an assistant surgeon before getting his medical license in Pennsylvania about 1932. He had two brothers and four sisters, all born in Portland. In 1932 his brother Clarence was in Russia working as a consulting mining engineer for the Russian government; and his brother Henry was in Berkeley, California working with McKee Radio Company. His sisters Frances, Alice and Dorothy were unmarried. His sister Helen was married to Andrew Y. Wu and they were living in San Francisco.

In 1932 William was applying to go to China to work as a professor of Anatomy, Associate Surgery in the Hackett Medical School in Canton, China. The school was established under the Presbyterian Board of Foreign Missions and he had a five year contract. His application witnesses were his mother and Mrs. William S. (France A.) Holt. Choy Lain, William’s mother, was born in San Francisco about 1884 and had never been to China. Her husband, William’s father, died about three years previously. Mrs. Holt testified that she had known William Poy since he was a baby and that William’s father was the first Elder in their church. Mr. Holt married William’s parents.
In August 1937 William applied to leave the U.S. so he could accompany Dr. Loh Shau Wan to Vancouver, B.C. Dr. Wan had original planned to stay in the United States for six months but was returning early because of war conditions in China.
The Reference Sheet in William’s file lists three of his siblings: Jue So Ling (Clarence Poy), file 5017/452; Helen Poy Wu, file 5006/397; and Jue So King (Alice Jue Poy), file 5017/760 There is no more information about Dr. William Poy in his file after 1937.
