Dear Don: I haven't a clue about the time ex-Vikings became Kerrymen I do know quite a few of them who settled in Donegal eventually became some of my ancestors. Over more time, when the Galloglass couldn't find their usual work involving mayhem, they got into farming and some of them would up or already were in Kerry. So, I suppose you're right, if not immediate, then eventually.. Love, Jack Sweeney where it's about to thunder, Palmer, Pennsylvania.
