I am trying to find info on my gggrandfather, Dennis DUFRAIN. He moved to the US in 1872. The info I do have is he was born in Three Rivers, Canada (according to son's birth record), He married Etta C LULL (or Clara Etta) 17 Jan 1891 in Weare, NH. On his marriage record his parents are only identified as Frank and Louise. He died in 24 Nov 1901, His death certificate lists his father as Francis, but has his mother blank. He was naturalized in the US in 1890.

I have conflicting birth years ranging from 1860-1866 based on the ages in the sources I found.

I understand that his first and last name spellings could have been changed when he came to the US, and I've been searching the spelling Dufresne. With so little info before he moved here, I'm not having much luck. I don't know much about searching the Canadian records.
