I'm looking for any information about a family from China with the surname Leon Sing. One relative would have left China to live/work in the Caribbean specifically Trinidad. The only information I have is a male with the surname Leon Sing was born in October 1863 and immigrated to America in 1882. He was a boarder with a Mr. Hop-lee who had immigrated to the US in 1878. Leon Sing worked in the laundry that was owned by Hop-lee.
The only other piece of information I have is that there was once a Fong Leon Sing's Grocery in Morvant, Trinidad in 1969.
I would appreciate any help.
