Miss Brydges

"Charles is also believed to have had a daughter prior to his marriage with Henrietta Maria. Her name was Joanna Brydges, born 1619-1620, the daughter of a Miss Brydges ("a member of a younger branch of the ancient Kentish family of that name"), possibly from the line of Brydges of Chandos and Sudeley. Joanna Brydges, who was provided for by the estate of Mandinam, Carmarthenshire, was brought up in secrecy at Glamorgan, Wales"
