I think I found the same family of Cheney's, I grew up in the villiage of Mountain, Ont and we had a hired man Earl Bylow (spelling of last name may not be excact)but close. I remember meeting his sister from Morewood. Her name was Massey who was married to a Cheney.There is also a couple of families still live around Morewood.
There is also a branch of Cheney's that went into Stormont, near Cornwall around 1880 that married into the Roach/Roche
family. I have several records on these families. They marry into many different french families
