Looking for any information on an Amy Driffel, born England circa 1804, and buried 4 April 1892 in Union Cemetery, Cobourg Ontario. She is buried with my Gt. Gt. grandparents John and Rachael Mitchell, per the cemsearch database in the local library. She is not on the tombstone and I have no idea who she is. Informant on the death certificate is Ann Jex. Any help would be appreciated.
