Hi
There is a licence for their marriage 23 Dec 1746 Francis age 28 of Deveroux Crt Middlesex and Elizabeth of St brides Fleet st ,age 21 years.
She was baptised at Croydon St John 28th July 1724 .born 20th
Parents Guy and and Alice
Guy married first at Croydon Mary Vincent 25 Sep 1718
Secondly as Guidon to Alice Kirril 30 March 1722 at Lee Kent.He was of Croydon Doctor and she of Langham,Beckenham .She was buried at Sevonoaks 28 March 1765
He was buried St bride Fleet St 29 Nov 1747 age 65 years MD (so a Doctor?)
That year his Land Tax record gives him as Gough Square Farringdon without off Fleet Str £6.
Children John 30.7.1723 Croydon-28 Aug 1730 ,Elizabeth 1724,Charlotte 14 Sep 1725,Mary Magdalen 23 Sep 1726 ,Frances 25.11.1727- 10.9.1730 ,William 25.7.1729 ,Henry 4 Jan 1730 , Penelope 1.8.1731 and Theophillus 1.Jan 1733 St Brides
There is a Peter Rouffignac also buried at St Brides 4 Jan 1746 age 64 a Reverend.
It does look like Peter is his brother and his father is Jacob de Rouffignoc .Jacob made a Will proven at PCCanterbury 1721 which names Guy and Peter and their sister Susanna.Helpfully he gives his parents as Thomas de R and Mary de la Motte.There is lot on his religion and his fleeing from France .He seems to be quite rich and there are properties mentioned.
Jacob born 6 Jan 1640 • La Rochefoucauld, Charente, Poitou-Charentes, France
Not having a lot of luck with the Davies's. Sorry
Does that help?
