The name you mention is so close to someone I recently discovered in my family tree.
John Allen FETTERLY (1888-1965) lived in North Bay, Ontario and is buried in Terrance Lawn Cemetery, North Bay Nipissing County, Ontario. He was married to Matilda E MCFADDEN (January 25, 1893 - October 1967) She is also buried in the Terrance Lawn Cemetery in North Bay.
Matilda was daughter of George McFadden & Sarah Wilhelmine Scott who married in 1890 and moved to Trout Creek in 1891 and had 8 children, 6 of whom lived to adulthood. Trout Creek is just SE of North Bay.
Other than that, I know absolutely nothing of John Allen Fetterly and his wife Matilda.If this is your line, could you let me know :-)Email: firstname.lastname@example.org
