William Lockhart was born in Wallingham in Surrey on 22 August 1820, the son of an Anglican priest, and died in St Etheldreda's, London on 15 May 1892. He matriculated at Exeter College, Oxford, and received a BA in 1842. He became a follower of John Newman, and joined him at Littlemore immediately after graduating. He converted to Catholicism in 1843, two years before Newman, who commented on the event in his last Anglican sermon, ‘The Parting of Friends’. In 1845 Lockhart entered the Order of Charity, founded by Antonio Rosmini, the nineteenth-century Italian philosopher and Catholic priest. Subsequently, he studied in Rome, became Procurator-General of the order and was rector of St Etheldreda's, London.
