This photo was in George Chock’s photo album, and had the date 7 Feb 1943 on the back, but the people were not identified. Fortunately, Bob Chinn has identified them for me (thanks, Bob!),
These are the children of Wilfred and Violet Chock.
Left to Right:
Wallace Chock, James Chock, Bertha Chock Fong, Marjorie Chock and Evelyn Chock Mun.
