This Cary family is NOT in my family at all. I presently live in London and in reading a book regarding London cemeteries, there is listed a Robert Cary (1681-1751) who is buried at St. John-at-Hampstead in the village of Hampstead which is probably a borough of London. At any rate, it is very near Central London. The cemetery is at the St. John-at-Hampstead Church. There is a monument to the Hart-Cary family and William Hart who d. 1717 is designated as a Salter, and was joined by the Virginia merchant Robert Cary (1681-1751) and his family.
That is all the info that is given but thought it might be a birth and death date of someone a Cary researcher may want.
