Ok, since I had not picked nothing in the British Isles since ToG, I decided to give it a go ... with just two rules ( and Ironman ):
- Always Catholic ( I could had gone Cathar twice ... it would made stuff faster, but more dangerous )
- No Jew cash
Anyway, it was a pretty standart run of forget claims, first to get the other county of the petty Kingdom of Tara ( while waiting for our esteemed father to kick the bucket and to stockpile enough money for mercs ), then towards the petty kingdom of Munster ( BTW by all logic Murchad had to have a weak claim on it since our grandfather was the ruler of it and our mother already died ... ) until we could usurp it.
I had some tense moments due to lack of money while with mercs hired ( due to a forged claim I could simply not refuse at that point ), but the fact I was allied with the King of Sicily meant that I was getting papal funds all the time ( due being part of holy wars vs muslims made by the Sicilian kings ), so it was not hard to recover from that. And after getting the totality of the Duchy of Munster I had enough of counties to create the Eire ... and from there it was easy to convince the counts of the North to submit voluntarily. The only one that needed military persuasion was the petty king of Connacht, but that was a fast and quite painless war. So, in 1094 ...
TBH I could had got it earlier, but as this was Ironman, it meant that stuff did not go quite as planned. First was the fact that Murchad decided to die ten months away of me having enough cash to create the Kingdom of Ireland ( well, he was infirm and ill for a couple of years , so he actually surpassed my expectations. But still ... just more ten months, man

) and his sucessor had not enough piety to create it ( so I had to buy some or wait ... I decided to buy it, since I would recover the cash faster than the natural piety buildup ).
The second reason was this Paradox luck magnet:
Our first son Domnall ... what a waste. He was not exactly the best chap around ( randomized stats, since he was in game start ), but as he was lustful like his father and had a decent stewardship, I got him to marry a nice genius girl...
That died in childbirth of a non genius girl not even a year after
So I married him to another genius girl ...
That died of illness a month after the marriage
Not learning with the previous examples, I married him to
yet another genius girl ...
And then he becomes celibate
And then his only daughter dies of illness at 5 ...
And then he gets a brick in the head :/
Actually that might had been for the best, since the second in line, the would be King Énna I, while not gifted in anything in particular, is married with a princess of Sicily and our crown prince in 1093 has claims down there . So, if I decide to continue, it might get interesting ...
On other news:
- England has been back and forth between the Godwins and the Norwegians ( ATM is norwegian ). William the Bastard was king of a couple of weeks and ended in norwegian dungeons. Scotland is still as united as ever ... that is, it isn't
- The big news is the fact that somehow the 3 Iberian brothers decided to use their forces to attack the muslims instead of eachother

Castille got Galicia and conquered all of
de jure Portugal while Leon and Aragon also pushed south.
- The rest of the western world is pretty much in tthe same way ( except for India, but I have not took any attention of what was going on there ... )
I might continue this game. The perspective of Irish in Sicily is quite enticing
P.S If you want a sugestion for another ( slightly more dificult ) game, 1 Sept 1095, Duke of Portucale. Create the
de jure Kingdom of Portugal while not being gobbled by the Almoravids. The fact that you are married with a 14 yr bastard princess is also of note ...
