I have seen a copy of my family crest(Swint) that matches the McSweeney crest. I am aware that many of the clans started leaving ireland in the 1500's. My dad says our name is Dutch, my grandma used to tell me it was Irish. Well, it definately doesn't look irish. I have seen countless variations of both names and I'm curious to know what the connection is. It's certainly possible that any Irish families arriving in Holland back then could have changed the name to blend in with the protestant surroundings. Over the years it could have just blended into a Dutch friendly variant. Then again, arriving in America with a boatfull of Dutch immigrants could have explained the name change. If anyone has some information that could help clarify this or at least point me in the right direction that would be great.
