Francis Bacon was born in Ireland, but not of Irish parents, he did not grow up in Ireland, and he did not consider himself Irish. So I do not count him as a contender for my exercise.
Sean Scully is a contemporary abstract painter of renown, and his works are held by many major museums. He was born in Dublin, and now his paintings may go for $600,000-$800-800. To me they seemed like a bargain, in the 1990s, at one tenth that price. I like his work, but to my eye he could just as easily be a “New York painter” and in a way he is. He even pops up on Google as “American artist.” His family moved to England when he was four years old, and Wikipedia calls him a “British artist.” Whatever.

And dare I confess that I prefer my Irish artists not entirely cosmopolitan? Here is one image of his:
