Samuel Heywood was born in Liverpool, the son of the banker Benjamin Heywood. He died at Tenby (Wales) on 11 September 1828, having been seized by paralysis while on the circuit at Haverfordwest two weeks earlier. He was educated at Warrington Academy (1768–72) and at Trinity Hall, Cambridge. Called to the Bar at the Inner Temple in July 1772, and made a serjeant-at-law in 1794, he completed a successful legal career as Chief Justice of the Carmarthen circuit, having been appointed in March 1807.
