I am surprised the family is from Co Tyrone since Edw III is buried in a Catholic cemetery.They would've been living quite dangerously, literally, as N IRE was predominantly Protesant [Presbyterian], and the issues are still ongoing.After abt 25yrs I gave up on my Co Tyrone ancestors...hope YOU are successful!
