I have a transcript of Sophia Amlaw's will, she died in Manchester N.H. as did Joseph. Also have transcipt of their tombstone, and census entries. you might find it useful. Didn't know Sophia was Native American. Pelky is actually Peltier, French. At least that's closer than Hamelin = Amlaw!!! I always felt that Joseph was the brother of Charles Amlaw( married Adaline Dumont), they lived next door to each other on lake Champlain in 1868 (property owners map) and were both Boatmen on the lake and they both moved to Manchester at the same time, but lately I came across info that Charles died in 1907, in Manchester and his birthdate was only 6 months off from Joseph, so who knows! Anyway I'm in touch with another Amlaw in Manchester who has done some good research and hope to hear more soon.
Also (this is so embrassing!) I'm afraid that I may be responsible for that GEDCOM that you were trying to confirm, I accidently posted the wrong one, the hypothetical one, and tryed to delete it immediatly but.... I keep one gedcom with proven facts, and another for working hypothesis. I don't know that Nicholas was the father of the Jean Baptiste Hamelin who was Charles Amlaw's father. I only know that Marie Francoise Sulliere(J.B.'s wife) had a sister named Marie Barbe Sulliere and that she married Jaques Hamelin, son of Nicholas. I drew a working hypothesis based on that, surely didn't mean to publish it!!! Sorry if my stupid error caused anyone to waste any effort!!! I promise not to post anything more outside my little website! Maybe I should just shutup and quit trying, I don't know.
