Musician Seegars Crew.
His wiki entry needs to be updated as its scant and not too good. I know he attacked slaver ships,did he let them loose afterwards or something?? No idea if he was an anglo Irish or of another descent but it was common for Irishmen to sail with the Royal Navy or Merchant Navy as Ireland was considered a dominion and part of England for Naval sake of that period.

Good information on Seegar:

He had a good nature and unusual kindness, England didn't believe in torturing victims unless they couldn't otherwise be persuaded. This also led to his undoing. He was deposed for freeing a captured merchant captain, and died a beggar on Madagascar.
I did read somewhere that he was Catholic so that would be unusual if he was Anglo Irish but not impossible.
However the surname Seegar is not common in Ireland :http://www.surnamedb.com/Surname/Seegar
Another Famous Irish Pirate Anne Bonney was born Anne Cormac in Kinsale County Cork, Ireland, the daughter of a servant woman, Mary Brennan, and her employer, lawyer William Cormac, whose cunning wife soon discovered the affair. Fleeing the scandal, William Cormac, Mary Brennan, and young Anne sailed across the Atlantic, to settle in Charleston, S.C.
