I don't think this will be of much use to you, but you might be able to help me. I have JOHN BEATTIE born c. 1864 whose father may have been JOHN BEATTIE on the 1857 Griffith Valuation of Drumhaggart, Parish of Burt, Co. Donegal. Moville is an adjacent parish.
My grandmother (MARY ELIZABETH BEATTIE) was an orphan in 1901. She is said to have had nine brothers. I only know two names Thomas and William. Family lore suggests three of the brothers emigrated to the USA after WW1. I was hoping your family had some rellies from the old country turning up 100 years later in the same area. As you can see, I am real desperate. Other names associated with Beattie, WILEY, McNAUGHER, BELL and maybe ARMSTRONG.
The Beattie surname does not seem to be as prevalent in Co. Donegal as it is further north.
Good luck with your family.
