In 1719, he was appointed to the sinecure position of rector of Llansanffraid-ym-Mechain, Montgomeryshire.^[2] From 1690 until his death in 1743, he was chancellor of the diocese of St Asaph, in succession to his uncle, Hugh Wynne.^[1][2] He became a canon of St Asaph's Cathedral in 1691 and chancellor of the cathedral in 1693.^[2] During his life, he was a supporter of the Society for the Promotion of Christian Knowledge and of the charity school movement.^[1]
