Elizabeth Dupre, wife of John (Jean) Frecker

[prufrockster]

I would appreciate any information on Elizabeth Dupre, first wife of John (Jean) Frecker. My information has Elizabeth being born in Guernsey on 26 April 1744 (baptised on 27 April). She married John Frecker (b. 13 July 1737, Gosport, Hampshire. d. 16 April 1812, St Peter Port, Guernsey). They married on 27 August 1761 in Westminster, London. They had 8 children, all born in St Peter Port except for eldest child, John (born in London). Elizabeth died in St Peter Port on 09 November 1779.

I would be particularly interested in any details of her parents.
