You need some help from someone who knows a little bit about Welsh history and geography. I appreciate making a mod is a lot of work so, anyway, allow me to come to the rescue a little bit. I am going to edit some of the files and post them on here, perhaps you can make a patch or something. FYI the Welsh royal family is utterly wrong and disappointing really because the material you need is right at hand thanks to something like Wikipedia. Llywelyn's father was Gruffudd and he had only one daughter, Gwenllian, never a son. His brother, Dafydd, did have two sons and several daughters. Llywellyn had two further brothers, one older (Owain) and one younger (Rhodri).
The regions of Wales too are annoying to say the least... let's go for consistency. If you are going to call areas after Welsh realms why go and call one "St. David's Region" when really it ought to be called "Dyfed". Deheubarth without Dyfed is actually called "Seissyllwg"... The banner used by Wales under Llywellyn was a quartered red and yellow flag 'countercharged' with lions 'guardant'.. the "red dragon" flag you use is a version of the one raised by Henry Tudor in 1485 some two hundred years later.
The correct flag of Wales (and it was never called "Kingdom of Wales" it was the "Principality of Wales") is here:
And whilst I am on it... "Sutton Hoo Province" ???? This is the name of an archaeological site... the area you have identified is part of Essex and Suffolk. You have spelled "Surrey" wrong as "Surry" and given the modern administrative name of "Argyle and Bute" as the name of a town, call areas such as Kent names like "Kent Region" which is totally unnecessary (because it is a county so obviously it is a "region") there are loads of other examples like this... the list goes on and on.
The files beneath amend some of the worst geographic errors and make the Welsh royal family realistic. Users will need to identify the correct files in the appropriate mod folder and then replace them with these:
descr_names.txt
imperial_campaign_regions_and_settlement_names.txt
names.txt
descr_strat.txt
I don't want to wind anybody up but this needed to be done!
