He was made rector of St Peter and St Paul's Church, Lavenham in Suffolk in 1644; and before he received that appointment he seems to have officiated, perhaps as curate, at Sudbury.At the Restoration he signed the declaration required by the Act of Uniformity 1662, and on this account he was the subject of a libellous attack, published in 1665, entitled Covenant-Renouncers Desperate Apostates.
