Hancorne was given the rectorship of
St Donats on 13 July 1674 and
Llandow on 16 December 1681, and was appointed as the curate of
Monknash on 17 November 1687. He left all these posts in 1707. On 18 April 1710, Hancorne gave the
county of Swansea's assize sermon (
The right way to honour and happiness), during which he complained of the "rapid growth of deist, freethinking and anti-trinitarian views." The targets of his wrath were "irreligion, profaneness and immorality", as well as the "curious, inquisitive sceptics" and the "sin-sick tottering nation". Later, he engaged in a campaign to reassert
tithe rights. The
Hancorne family were involved in the "Sea Serjeants", led by
Sir John Philipps, 6th Baronet. Hancorne is commemorated for his restoration of the chancel of the
Church of the Holy Trinity, Llandow in 1712. On 17 June 1718, he was made the prebendary of
Llandaff Cathedral, Prebend of St Dubritius, which he retained until his death. ==Death and legacy==
