Samuel Sebastian Wesley was an English organist and composer. Born in London, he was the eldest child in the composer Samuel Wesley's second family, which he formed with Sarah Suter having separated from his wife Charlotte. Samuel Sebastian was the grandson of Charles Wesley. His middle name derived from his father's lifelong admiration for the music of Bach. After singing in the choir of the Chapel Royal as a boy, Samuel Sebastian embarked on a career as a musician, and was appointed organist at Hereford Cathedral in 1832. He moved to Exeter Cathedral three years later, and subsequently held appointments at Leeds Parish Church (from 1842), Winchester Cathedral (from 1849) and Gloucester Cathedral (1865-1876). He died at his home in Gloucester on 19 April 1876 aged 65. He is buried next to his daughter in St. Bartholomew's Cemetery in Exeter by the old City Wall.
