I worked on this line, which is my husbands line of the tree for quite a while.
In the hunt for info I ran into a Earl Close and he was a wealth of info!he sent me via snail mail a large package with the history of the Payan dit St Onge family. MAps, dates, bios.. it is all there.
His info is as follows..
Earl Close 415 E glenhurst Dr Tuscon AZ 85704
All of the info he sent me is from a book but I am not sure the name of the book.. wish I did. BUt there is an entire chaptercalled.. Historical St Onge Background and it is a wellspring of info.
