Thanks for the information. I think he might be related to the French Vonoven branch. Do you have any indication that he or his ancestors were Jewish?
Why was he called William in the 1880 census? Are you sure that this is the same person? He states his age as 23 which would mean that he was born in 1856/57. In other census records about
Gaston I find his birth year as 1851. Also I do not find a daughter called Mary. Couldn't it be that this William was a younger brother of
Gaston?
It is also strange that
Gaston reports different years of immigration and naturalization.
I do not see the connection with John
Koontz (given that he was
Dutch I guess his name would have been Coensz. or so). They were neighbours, but why would they be related?
Do you know if there are any living descendants in the male line of
Gaston Vanoven (so males with the name Vanoven)? In that case, with a simple DNA test we would know if our families are related (see
http://www.smgf.org/)
