Hi Helen,
Thank you. All of the references you provided are helpful.
I'm particularly interested in correctly identifying his wife's first husband (Wikipedia calls him Henry King; but the soc.gen post called him Major John King. Alumni Catabrigiensis calls her "Anne Hannah King, widow," but is silent as to her King husband.
While it is only a referenced item, entry below may for now be sufficient to confirm he was John King. Roughly,
Attested copy of conveyance (feoffment), RAPER/245, In consideration of £480, from Sir Thomas Millington of Lincolns Inn Fields, co. Middx., kt., and Ann Hanna, his now wife (formerly wife of John King, dec'd), to Thomas Miller, citizen and alderman of Chichester, 23 Nov 1687; Property as in no. 244 but described in different terms; held by West Sussex Record Office; see The National Archives.
Edited to add: Alumni Catabrigiensis also does not identify her as the daughter of Sir William Russell. His daughter Ann is "wife of Sir Thomas Millington of London, M.D." in "Russell of Strensham"; see Thomas May, Gregory King and Henry Dethrick The visitation of the county of Worcester ... begun 1682 ... finished ... 1683 ..., 84; digital images, InternetArchive.
