The son of a distinguished father of the same name, Giles Fletcher was the brother of Phineas and cousin of Richard Fletcher the dramatist. He studied at Westminster School and Trinity College Cambridge (B.A. 1606, Fellow 1608, M.A. 1609, B.D. 1619). Giles Fletcher was ordained in 1613 and in 1617 was made rector of Helmingham, Suffolk, afterwards moving in 1619 to Alderton in Suffolk, where he remained until his early death in 1623. Misled by the entry in Phillips's Theatrum Poetarum (1675) William Winstanley later invented a third Fletcher brother named "George."
