Sir Barnaby Fitzpatrick, 2nd Baron Upper Ossory (1535? – 11 September 1581), was educated at the court of Henry VIII of England with Edward, Prince of Wales. While he was in France, he corresponded regularly with King Edward VI. He was active in suppressing Wyatt's rebellion in 1553. He went home to Ireland, where he had had a lifelong feud with the Earl of Ormonde. His wife and daughter were abducted in 1573 by the Grace family, supposedly at Ormonde's instigation. He killed his cousin, the rebel Rory O'More in 1578.
