Like I said, you probably mean that Saint Patrick wasn't Irish, he was Scottish by birth.
It's one way to do an end run around the problem of the Apostolic Succession . . .
Of course, the problem with this theory is that St. Patrick was educated and ordained to the priesthood on the Continent (at Auxerre in Burgundy), and his boss St. Germain chose him to accompany him when he was sent by the Pope to convert the Irish.
