an English bishop of Clogher in the Church of Ireland. In 1751 Garnett went to Ireland as chaplain to the Lord Lieutenant, Lionel Sackville, 1st Duke of Dorset. In 1752 he became Bishop of Ferns and Leighlin; he was translated to Clogher in 1758, and remained bishop of Clogher until his death. The only work of Garnett, besides some occasional sermons, was his prolix Dissertation on the Book of Job (1749; second edition 1752).
