Born at Much Lees, Essex, he was the eldest son of John Townson, rector of the parish, by his wife Lucretia, daughter of Edward Wiltshire, rector of Kirk Andrews, Cumberland. He was educated first under the care ofHenry Nott, vicar of Terling, and next at Felsted grammar school. He matriculated at Christ Church, Oxford, on 13 March 1733, and was elected a demy of Magdalen College, Oxford, in 1733, and probationary fellow in 1737. He graduated B.A. on 20 October 1736, M.A. on 20 June 1739, B.D. on 13 June 1750, and D.D., by diploma, on 23 February 1779. He was ordained priest in 1742, and, after making a tour on the continent, resumed tutorial work at Oxford. In 1746 he was instituted to the vicarage of Hatfield Peverel, Essex, and in 1749 he was senior proctor of the university. Resigning Hatfield in the latter year, he was presented to the rectory of Blithfield, Staffordshire, and on 2 January 1752 he was instituted to the lower mediety of Malpas, Cheshire, where he thenceforth resided. In 1758, when he received a bequest of £8,000 from William Barcroft, rector of Fairstead and vicar of Kelvedon in Essex, he resigned Blithfield and applied himself more especially to literary pursuits. On 30 October 1781 he was collated to the archdeaconry of Richmond, and in 1783 was offered by Lord North the regius professorship of divinity at Oxford, which he declined on account of age. He died at Malpas on 15 April 1792.
