Hi Bill1, You do come from an illustrious family
I will give you what I can.
Mary Ann Rolfe you have to be careful of because there are two mary ann rolfes, one my great x 3 times grandmother and the other her Aunt and they both married Joseph Strutts. By the information used its obvious you have her death certificate4. This place of birth is a mystery because the earlier census material gives her birthplace as Whitechapel Middlesex.
Jemmima and Rachel were the Dughters of Joseph Strutt the Record Keeper to the Duike of Northumberland at Sion House ion Isleworth. his father was Joseph Strutt the famous antiquitarian. If you send me a email address I hav be a lot of links I can send you with information.
