Lady Frances Hunter, death record, 1765.
I have a copy of "The London Chronicle or, Universal Evening Post" Vol. XVII, No. 1279 dated from Thursday, February 28, to Saturday, March 2, 1765. It lists the following death: "Wednesday died, in her 97th year, at Bromley, near Bow in Middlesex, the Lady Frances Hunter."No more info, but I hope this helps someone.
