I'm sure you've seen the gravestone, but just in case:
https://www.findagrave.com/memorial/96411029Abraham's burial:
Drouin collection (Church of England)
Refers to him as a senior farmer, died on the 12th, buried on the 15th of January 1877. Witnesses were Johnson Tuplin(?) and James Bryan (Maybe Tuplin is a son in law?)
In the index of Quebec, Canada, Land Grants, 1763-1890: I could find two entries, but very possibly only one is yours. I kept bumping into another Abraham Bryan in the Quebec notarial records that went well past the year that yours passed away.

It looks like the government hasn't put the years you need online yet, but they are on microfilm. Read the guide here for instructions:
