A certain Brian O'Connor, who I'm fairly confident didn't exist (well, no-one by that name was King of (Gaelic) Ireland in 1271 or whenever it starts) And is wife is named Jill. Maybe they're confusing him with Brian Ua Neill, who died a few years before IIRC.

The Irish unit roster is good though, looks more "historical" than I anticipated. Too much heavy armour perhaps, and they shouldn't have lancers. And a cav archer wouldn've been nice. But all-in-all it could've been a lot worse, I feel.
