Glad I could help.
Unfortunately finding marriages records in Canada is pretty much a matter of luck - no telling which parish people were married in and the marriages weren't copied into other parish records.
I think this is the Ephram Senecal married in Notre Dame in Granby in 1844. The Treffle SENECAL is listed next door; probably another son.
