introduced Peat to the elderly and Catholic, Jane Smith, a kinswoman of Maria Fitzherbert. Jane had been the sole heiress to the County Durham estates of her father and lived at Herrington House, East Herrington, near Sunderland. She was wealthy but is also described as eccentric, a miser and a kleptomaniac. Peat had been appointed as one of the many chaplains to the Prince Regent in 1800. He wrote to the Private Secretary in 1813 requesting an audience with the prince as he had never met him. suggests Peat was supportive of a match with Jane in order to use her relationship to the prince's unofficial wife, to further advance himself in royal favour. The source also suggests that Jane was taken with the idea of a title if she were to marry Peat. Whatever their reasons, the couple were married on 6 November 1815 at St Michael's Church, Houghton-le-Spring. Peat had tried to introduce his wife to fashionable society in London, but as she was seemingly unfit for it, he returned her to Sunderland. He lived apart from her at his vicarage in New Brentford and visited her just once a year. Peat's other royal connections included being mentioned by Mary Anne Clarke at her public enquiry, as having attended the theatre with her one night, but he was not involved any further in the case. Peat was one of the stewards of the 49th birthday celebrations of the Duke of Kent at Fishmongers' Hall in 1816, but did not attend in person. He was also Deputy Grand Chaplain of the Orange Order and present at a meeting alongside the Duke of Cumberland.
Death and legacy
Peat died at the vicarage of St Lawrence's in New Brentford on 20 April 1837, aged 65, and his library was sold at Sotheby's on 23 and 24 June. On hearing the news, his wife is said to have "bought a new dress of bright yellow cotton, and a bonnet, a feather, and ribbons to match" and walked the streets of Sunderland celebrating his death. She died in 1842, aged either 91 or 92. Samuel Wesley called Peat "an old Acquaintance, & I may even say Friend of mine. He is the Parson of Brentford, a good Scholar, a very feeling Lover of Music, a Man of superior Manners, & what we think better than all these, his Heart is warm and sincere". The Monthly chronicle of North-country lore and legend describes Peat as "a fine-looking little man, dressed in a coat and waistcoat that might have been made by a Stultz, a white necktie, knee breeches, and white silk stockings. He cut a good figure on horseback, being an expert rider." Moses Aaron Richardson's The Borderer's table book describes him as "highly distinguished for his accomplished manners and gentle manly bearing, an excellent scholar, and a warm and devoted friend." However William Benbow's ultra-radical and anti-clericalist pamphlet The crimes of the clergy accuses him of being "proud, tyrannical, and overbearing", arrogant and a liar.
