Hi Listers: Am looking for any connection to my grandfather, Johnston Mahaffey, born September 24, 1876, in Castlefinn, County Donegal, Ireland. His mother was Sarah Johnston and father was James Mahaffey. Johnston Married a McCausland and moved to Newtownstewart County Tyrone, NI. I have no other information on my great grandmother Johnston. Thanking in advance for your help! Libby
