I've got an old map showing Ireland in 1315 but its a little confusing in places as it shows some of the subdivisions on the land with names in brackets but its a bit unclear if it means they have them or had them. I can't create all the places exactly as it starts to create too many provinces and I'm already pretty close on that.. however my intention is to get one map with a lot of provinces and then create a second campaign with a reduction in provinces. The Butlers are a debate (I have one faction left) so they're going to miss the final vote and I'll probably split the central lands for balance. I'm trying to achieve a minimum of 3 regions for balance. Regions wont match historical boundaries as that may look nice but generally doesn't help the AI too much so its a bit of a trade off.
Similarly for the O'Briens from a balance point of view they may get Athenry as a third province.
Thanks for the additional info though its a great help. I'm mostly working on banners and want to get the strat models sorted out at the moment. Really need strat models which are in chain not full plate armour.
