Hi John,
I am sorry I missed your message. I am sure by now (some three years later) you have found the townland of Ballytyrone, in the parish of Loughgall, County Armagh, Northern Ireland. If you need more specific information on the location, just let me know. Have you checked the 1848 evaluation? Let me know, I have a photocopy of it I could check.
All the best,
Pat M.
