I think the Thomas and Jane(Gibson) McGaffin are relatives of ours; my husband's great grandfather was Thomas Gaffikin (surname as it appears on his marriage certificate), born 1850, who married Jane Gibson; they had a son Denis (my husband's grandfather) born around 1880 in Knocknamcukley but we cannot find a birth certificate for him. They moved to Scotland at some point (Denis married in 1906 in Scotland) and the surname was McGiffen by then. The surname seems to change to various options; we are having difficulty sourcing information/certificates on this side of the family;do you know how to access information from Knocknamuckley?
