In Mappa Regnorum on CK1 there was (is, still) a single county for the Anglo-Normans islands. I don't think it's necessary to split it into 2 different counties, these islands were too much intricated politically and economically a too remote to play such a big role in CK2 ... IMO of course.
But one more thing from the Axl's map Eireann is the genitive form of Eire right ? But it's usually used to translate Irish for official titles and not Ireland (i.e. from wikipedia : Irish Parliament = Dáil Éireann, while Ireland = Éire ). I guess it's a question that has already been tackled but it feels strange having an adjective form to designate the country (like English instead of England ...)
