Another name if we go with Ireland could be Ogygia. It is an ancient name that a greek explorer, Plutarch used in possible reference to Ireland. I also like Eire too, it's short and sweet and has a nice clear resemblance to where we may plan to base our region from. If we go for Ireland we may need to expand it a little bit to make sure we have enough to work with similarly how they did with Unova and how it was based off New York.

Also, having a look at the local mammals of Ireland, I have an idea for the animals the starters can be based off if we go with Ireland. We could have a grass deer, a fire squirrel (red squirrel) and maybe a water whale/porpoise as many have been spotted in Irish waters.
