George and James Mar – brothers of Roy Sing Mar, DDS (1927-2018) and Ruby Mar Chow (1920-2008), owner of Ruby Chow Restaurant and first Asian American elected to Seattle King County Council in 1973.
Mar King Sing 馬日勝 (Chinese name Mar Yet Sing) was the eldest son of Mar June (Jim Sing) and Wong Shee黃氏; (黃)巧云 . They had ten children; all born in Seattle, WA: George Mar, Jim Sing Mar, William Mar, Ruby Mar, Mary Mar, Alice Mar, Henry Mar, Roy Mar, Edwin Mar, Coleman Mar.

George Mar was born on 19 February 1915 but his birth certificate incorrectly states that he was born on 29 March 1915. He was applying for his citizen’s return certificate so he could be employed by the Dollar Steamship Line on their steamers to the Orient.
James Mar (Mar Jim Sing), George’s younger brother, was born 29 May 1916. He presented his Seattle birth certificate #12786 as evidence of his citizenship. He was applying for employment with American Mail Line and hoping to go to China with the company.
When they applied their father was visiting China and their mother, home in Seattle, was a witness for both of her sons. Their Form 430, Application of Alleged American Citizen of the Chinese Race for Pre-investigation of Status, was approved. They visited their father in Hong Kong and returned to Seattle on the S.S. President Taft on 12 July 1932.
