As several of us have already said, this topic should have been on U.S. board not Tyrone.
James' birth certificate, if any, will list names of both parents. If, as might be the case, he was orphaned at a young age and raised mainly in Ireland then the details about his father he gave on marriage might be incorrect.
You can search for James in
- 1910 U.S. census (Family Search)
- Philadelphia church records (Ancestry)
- incoming U.K. passenger lists (Ancestry & Find My Past)
Once you get more accurate details THEN you can search for him in Tyrone or Ireland.
