Henry Clifford, of Sittingbourne, Esq.

Not the same as George Clifford, 3rd Earl of Cumberland

Probated Will of Henry Clifford of Sittingbourne, Kent Mentions son George, and daughter.

.... I do believe that the aforesaid George is the son of Henry Clifford, Esquire, of Sittingbourne, and formerly of Bobbing, Kent. The smoking gun is Henry Clifford's will, which is housed at the British National Archives (but can be viewed online by the Archive's pay-per-document service), in which he leaves 50 pounds to George. The Clifford Association, which has taken a great interest and has aided in identifying our George, also alleges that a recently discovered deed for property sold/purchased in Hampton, NH, which was found in the Haverhill, MA library, also spells out that John is George's son. Furthermore, there is evidently a comment in the original record about John Clifford being a fully-grown man when he was baptized in 1646 at the First Church of Boston.
