Thanks for your input Milliepede
Yes Kitty Jane Milner married William Bingley in 2/6/1808 at Covent Garden. William died 1828. Not been able to connect Catherine Thomas. I wondered if she was Kitty and William's daughter?
Not been able to trace marriages, births or deaths for the other sisters.
Although in the Churchyard at Wycombe there is a headstone with the inscription:
"In memory of Charlotte, Relict of the late Lewis Duval Esq of Marazion, Cornwall; who departed this life 12 February 1845; in the 82 year of her age".
below if goes on
"In memory of Michael Milner and Harriet Kitty his wife of the County of York.
Also Sophia Milner their third daughter who died on 18 Nov 1845"
So there's got to be a family connection there somewhere. and why does it say County of York? Not found a connection there yet either!
Charlotte Duval fits with the 1841 census Ive found two marriage notices to Lewis for her one with her surname as Melvill and one as Vincent both same date.
Not expecting you to solve all my comments just thinking out loud.
I appreciate any thoughts, comments info.
Many thanks
