I think it was Elizabeth Zerega Pelham-Clinton who lived in/around London.Got the idea somewhere that is was at "Weathercock House" in High Wickombe, Berkshire (?), outside London.
Charlotte Z. daughter of John Zerega and Kathering Berry was reported to have died at the Hotel D'Albion, Hyeres, in France.She is buried at Woodlawn in the Bronx and her monument mentions that she was the wife of the "X" (Tenth)Baronet of Thirkelby. (Sir Frederick Frankland)
Sir Frederick had children by his second wife, who, I think was related to the Baroness de la Zouche.
I think it was a Frankland who was tax collector of the Port of Boston, or who represented the King in some capacity, at the time of the Boston Tea Party.
