It would be a little English people celebrating the 30th January 1649

Because that set it all in motion, didn't it?

Quite a few people do celebrate that date, and would like to celebrate a re- enactment of it on the third of that name.

But I think it had being going on for quite a while, names like Feach Mac Hugh spring to mind, then there was the bit before that... but certainly, the need to find (someone else's) land to pay off Civil War troops was a big factor in the NI settlement. I think, though, in any case, simple surplus progeny would have led to a similar class of come- down descendants hanging onto the coat tails of the establishment.
