George McElwain - Why not born in Pennsylvania?

This profile states his father died in Pa, but Thomas George was born in Va. Wikitree is cited as a source, and it states his father was born in Ireland and died in Pa. It then states that the Thomas George of this profile was born in Va. Seems more likely he would have been born in Pa where his father died.
