Thanks
Ive found Marys's headstone and it reads the following;
in loving memory of MARY GAFFNEY
Crossmolina and Cavan
died 21-oct-1990
aged 82 years
her son DICk
died 3-sep-1992
aged 56 years
She died in Crossmolina so do you think maybe Cavan was her place of birth? or maybe just the town she lived in for a long time? mind you she also lived in Middlesex for a while and there's no mention of that on her headstone? lol
