Dominick Kirwin was an Irish Confederate, fl. 1642–1653? Kirwin was a member of one of The Tribes of Galway, and led the raiding party that seized a ship anchored near Galway early in the morning of 19 March 1642. It was a British naval vessel under the command of a Captain Clarke, and had been sent to reinforce the garrison situated at Forthill, overlooking the town. The garrison and its commander, Captain Anthony Willoughby, had been harassing the locals and bombarding the town on a regular basis for several weeks, and negotiations had been held between Willoughby and Walter Lynch (Mayor), with the Earl of Clanricarde acting as mediator.
