My brother in law is from Guyana originally. I am trying to start his genealogical history for him but don't have a lot of information. His name is Mark Cumberbatch. He applied for naturalization in 1988. His father is supposedly living in New York somewhere. He hasn't had contact in a while. He has cousins in the US. I think he might have lived in New York for a while. He was also in the Air Force.
Do you know of this family?
Sincerely, Tracie Jones
