I'm just looking for absolute confirmation really. At the moment I'm working on certain hypotheses. Agnes Quigley and Michael Lynch are certainties, so I can work back from them.
Agnes definitely had a Kitty Ferry who was her mother, but there were probably a few Catherine Ferrys so I just need to confirm which is the right one through burial records, census or any record where I can match up dates etc properly.
I found the burials of a Kitty and husband Robert Quigley in Derry City (the memorial was on another tree on Ancestry), this is the family from Racecourse. This Robert died in 1939 aged 68 and Catherine died in 1958 aged 93. According to the burial info, this Catherine has parents Neil and Catherine Ferry.
I was told from handed down info that Catherine/Kitty was married to a John Quigley (ie not Robert), but that could be an error.
