Farkas, Max

I am trying to help a friend find her family.
Max Farkas B.1910-D.1980,Calif. Family legend says that he was born on Ellis Island,His mother landed and had to wait to be processed until she gave birth,I don't know parents names.The family was from Hungary.
Max married Gertrude Duckman B.@1905-D.@1976 and had David Franklin Farkas B.1947,Brooklyn,NY.This might have been his second marriage.
