Fred is not related, atleast not the same Fred, being John's son. Perhaps he is related, though, given both families lived in Presue Isle and Fort Fairfield around the same time. Here is all that I have. Luckily I still had the notes that I had copied from the census.
1900 Presue Isle census family 94
Fred Pelkeyb. 1/1868 age 32 married 10 yrs. Fleviewifeb. 10/186534 Ellendaub. 2/188010 Annie"4/18928 Mary J."4/18946 Emma"4/18954 Laura"9/18972
The census was taken in the summer I believe. Fred and Flevie were listed as born in French Canada. All kids born in Maine. Fred immigrated to the U.S. in 1874, Flevie in 1888.
