Sir Robert Peat (c. 1772 – 20 April 1837) was an Anglican cleric and, according to some sources, the first Grand Prior of the revived English langue of the Order of Saint John.
His obituary says that he was appointed for services rendered to that king by a relative of Peat and his entry in the British Herald says that this was in connection to land willed to him by a John Vesey of Warsaw.
[7] Appearing in court in 1808 after being attacked outside of the Drury Lane theatre, the defence objected to calling Peat "Sir" as he had not been appointed to any order of knighthood in the United Kingdom.
[16] Herrington Heritage suggests Peat was supportive of a match with Jane in order to use her relationship (albeit distant) to the prince's unofficial wife, to further advance himself in royal favour.
[15] Peat's other royal connections included being mentioned by Mary Anne Clarke (the mistress of the Duke of York) at her public enquiry, as having attended the theatre with her one night, but he was not involved any further in the case.
[21] 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.
"[22] Moses Aaron Richardson's The Borderer's table book (1846) describes him (from local papers) as "highly distinguished for his accomplished manners and gentle manly bearing, an excellent scholar, and a warm and devoted friend.
