Background
Grayle was the son of John Grayle, priest, of Stone, Gloucestershire, where he was born. Brook states that Grayle, having married, in the end of 1645, a daughter of Henry Scudder, went the next year, probably as minister, to live at Colling-bourne-Ducis, Wiltshire.
Career
At the age of 18 he entered Magdalen Hall, Oxford, as a batler, and proceeded Bachelor of Arts in 1634 and Master of Arts on 15 June 1637. He subsequently became rector of Tidworth in the same county. Grayle died, aged 40, early in 1654, after a lingering illness.
He was buried in Tidworth Church.
A son of the same name, educated at Exeter College, Oxford, was rector of Blickling, Norfolk, and published sermons.
