Thanks Power. (Can I call you Power?) I sort of knew right off that putting together a kit would be a pain, but growing up with a certain pride for my Irish heritage sort of made me "one of those people."
From what I can tell, there was heraldry that went on in Ireland, but I cannot say for sure when it took place or in what specific capacity the form took. I'll post those questions in a separate thread to keep everything copacetic. The fact that Irish history is so varied with many distinct cultures makes finding something that is period somewhat difficult.
As for what type of Irish I was looking for, I cant really say. And that is something that I'd like to learn more about. I know for certain that I don't want to portray an Englishman living in Ireland during the attempted conquest, but I also know that other cultures, namely the "native Irish," the Hiberno-Normans, and Cambro-Normans existed there as well. I honestly could not tell you the difference between them; I find it's easier to contemplate black holes and string theory.
And since you've pointed out that there is little evidence for the better part of 200 years I do have some theories as to what the Irish might have worn. To me, it is certainly plausible for the Irish to wear what other cultures (namely England) would have worn. If they did have their own "style" of armor (and it makes sense that they would) I think it would likely have Scandinavian/Viking influence. I am also not opposed to changing what little story I have for my persona to satisfy my choice for armor. But for now, I think a concise history of Ireland, outlining the different groups of people will be a start to my research. Thanks again for all the help.
