I don't have answers for all of 'em, but I have different answers than those given so far for a few:

2) (d) -- deValera: not because of his Spanish surname, but because he was a US citizen, born in Brooklyn.

6) (a), I think; if not, it has to be (b). That particular funeral speech is famous as a prelude to the 1916 Rising, and I'm pretty sure that the famous (or soon-to-be famous) speaker has to have been Pearse or, if not, Mick Collins.

8) The first of the Bloody Sundays was when British armored cards rolled into Croake Park during a Gaelic football game to massacre a random selection of players and spectators in retalization for that morning's multiple assassinations of counterrevolutionary bigwigs. I'm not too good on dates ~ early 1920s?

The third was the 1969 incident; what was the second?

13) (b) probably is correct; (a) might well be one way of putting it, but is hardly an objective response. The Irish Civil War was a conflict between those willing to accept the Treaty (which included the Partition along with the establishemnt of the Free State) and those who refused and wished to continue fighting the British for control of the entire island by an independent Irish government(preferably, if not necessarily, a republic).
