Hello,
Do you mean Mulnagore ? I'm happy enough with Mulnagore, Carland.
It is mentioned a couple of times in the list of Landowners in Co Tyrone, 1876.
Mulnagore is a 291 acre townland in the Barony of Dungannon Middle, Civil Parish of Pomeroy and Poor Law Union of Dungannon.
I am surprised that you were able to find it in an Atlas. Usually you require a large scale map when you are looking for townlands.
Best Wishes, Christopher
