It's interesting to note that Celtic nations (like Ireland and Scotland) have a tendancy to put things in the future or the conditional tense where it would be in the present tense in RP. For example, instead of saying "Ah, so you're from America?" they might say "Ah, so you'll be coming from America, then?" (Scottish) or "Ah, so you would be from America, then?" (Irish) I'm not sure why this occurs, but I suppose that it's linked to the underlying grammar of the indigenous language.
As an aside, I think there exists a curious valourisation of "ancestors". I mean, Irish legacy is partciuarly reverenced in some areas of the US, for example, but not all of the immigrants were good people. Some of them were lazy, feckless and petty criminals. My point is that just because you're family came from somewhere in the world, that doesn't make it "good". It's nonsensical to think that way.
