I think a lot of people, particularly those from North America, don't realise how small Ireland is. You often hear of people from Ireland being abroad and someone saying 'Oh you're from Ireland, do you know...' at which point the Irish person will roll their eyes, and then actually stop when they realise they do, in fact, know the person being mentioned. Or at least knows someone that knows them. We also have a saying here: 'In America, 500 years is a long time, and in Ireland 500 miles is a long way'.

I've always been told "if you ever go to Cork, just say you're a descendent of Patrick S#######. Someone there will know him". 

That was my grandfather. I don't know how true that is but if I'm ever lucky enough to go I'm going to try it.
