Family lore says during the Famine my ancestor was new to a parish in West Waterford. Even though he born and raised we think less than 5 miles away for his entire adult life he was considered a Blow-in. Meaning he just blew into the parish. If he was called that to his face may I ask what as Gaelige the people of the parish would have called him?

In the dictionary there's this -
