Well, my uncle's name is Arthur Liang, but he was born in the 1940's and came to America when he was really young. My father is Matthew Heng Liang. He was born in 1944 and came over at the same time. I think they were living in Canton before they moved to the US, and i think my most of my grandfathers side of the family came from Canton. My grandmothers side of the family was Beijing based, but her last name was Kao. So... it's hard to tell if there is a link anywhere there. Those nicknames dont sound familiar to me, but I'll ask around my family and see if anyone remembers.
Thanks for writing!
