Adelard J Gamelin was my Great Grandfather. I was born in Epping NH. I saw the wooden grave markers in the catholic cemetary when I was younger. They are all rotted into history now. My last name is Desjardins. My dad was named Romeo he had five siblings. His mother was Eva Gamelin born Nov 11, 1904 in Hookset NH.
You said you have them in Mass with a child born July 11 1904. That is a clue. Eva could not have given birth to two children within four months, and have my grandmother stay alive at four months gestation. Also Delphine her sister was born in 1998 and there is no mention of her.
My grandmother Eva was probaly named after her mother Olivia Marie (called Eva, or Ewa). Olivia was married to Adelard. I have a picture of him smoking a pipe.
The info I have has Adelard born in Yamaska Quebec Canada in Dec 05, 1871. If you have his birth certificate and it says Guillaume and Eugerie Marie Vetu dit Belair announce the birth of their child on Dec 05, 1870 then who am I to argue. I would love to see it and anything else you want to share. Maybe we can sort this out together.
By the way, my mother told me about a man called Uncle T'fille, and you list a Treffle. Now that is very interesting.
