    A lot of canadian born ancestors it seems, like many northeastern americans. + He must have some welsh to, since his family is protestant with old british roots, the welsh ancestry is very undercounted in amaricans i think it’s because they get mistaked with english and also a lot of the names were altered so the Welsh could blend more easily with the elites that were made primarilly of English settlers.

      “This guy actually is an American dude. He is not an Irish citizen from Ireland. Having said that, his head shape, facial features and so on are extremely common in Ireland.”

      An American of English, Scottish, Irish ancestry.
      No offense, but I’m not exactly sure why you even posted that?
      It didn’t add anything to the conversation and was stating the obvious.
      I can’t understand how you can even take the time to post that when there are 100s if not 1000s of obscenely ignorant posts on this site and nearly all of them go unchallenged literally for years.

      I’m from the USA and basically everyone knows exactly who Seth MacFarlane is.

    He looks like a less attractive version of Dean Cain who is part Japanese. I thought this annoying guy would have some Asian in him.
