The following is TO A SIGNIFICANT DEGREE SPECULATIVE.
It will be revised when Judy Jerkins gets back to her files (and/or I do some serious research). Judy said that in 2011, and again in 2021.
John Courtoy (1727?-1818) (but there was another 1743?-1826??)
[Linda's possible G5F]
Born Nicolas Jacquinet, according to document Judy says she uncovered in the London PRO.
(Ron Courtoy of London purchased a file on Courtoy from the Public Records Office in 2003).
A Nicolas Jacquinet was born in Jussy in 1727 (northern France, 50km south of the Belgian border).
This family traces itself back to Edme Jacquinet b. 1642 and Françoise Petiet b. 1640.
[A second Nicolas Jacquinet was b. 1743 at Haroue, Meurthe-et-Moselle (350km E, N of Nancy)]
Jacquinet undertook an apprenticeship as a Wig Maker and moved to England 1750-54.
He achieved very considerable financial success, somehow.
Perhaps c.1766, aged c. 40, he changed his name to John Courtoy.
He was 50-75 at the birth of the nine children listed below.
So it's reasonable to assume that he had earlier children as well.
m?/p? Marianne / Mary Ann Woolley [Linda's possible G5M]
Children 1-2 (1777, 1780)
Children 3-6 (1784-1793)
p? Hannah Peters (c.1782?-1848)
A courtesan of some standing, it would appear.
Children 7-9 (1798?-1802?).
John d. 8 Dec 1818, aged 92, in Little St Martin Street, Leicester Fields, London.
John was bur. in London 16 Dec 1818.
Mary Ann d. Dec 1822 in London.
According to The Times of 31 Dec 1818, this John Courtoy left a very substantial sum of money.
And make what you will of this strange little piece.
Judy's sources were replayed in a piece by Celia J. Dodd (see 21.6), of the 9th child, mirrored here.
[Note: There may have been another John Courtoy d. in London in 1826, intestate?]
Hannah d. during the plague epidemic in 1848, and has a very special crypt in Brompton Cemetery.
Added Jan 2021: Judy drew attention in January 2021 to a book published under the splendid title 'Courtoy's Complaint', with several (informal) reviews. It was edited by David Godson (of south England), from the diaries of a Maureen Sayers during the Regency Period (1810s, 'Mad King George III's late years). It was published, possibly in an all-black-cover edition (bad) and a cover with the same cover but red-lettering (good), in November 2017.
This page is entirely based on Judy Jerkins' work. Judy has provided a summary web-page (mirrored here), but there are many other snippets in large numbers of her postings on various genealogy sites, and she has more documents that she hasn't yet had time to consolidate into a full story.
Judy has also documented a separate, well-to-do family of Courtoys (1645-1900).
