I have been researching another branch of this family. I have found an online correspondence referring to records that appear to show John m Susannah Wood as the son of Gabriel Adams. This certainly seems confirmed by the fact that Gabriel Adams had known sons Philip and Sylvester, and that Gabriel's son William of Fairfax Co also appears to have had a son named Sylvester. Although I have not seen the actual documents, this is a description of what should be looked for: John Adams of Lunenburg Co. and his wife Susanna sold 100 acres land in Fairfax Co. being the same tract willed to John Adams by his father Gabriel in 1750. This transaction was in 1758 and during the period t__ 1762, a John Adams and Susanna, his wife sold a number of parcels of land in Lunenburg Co., all being part of a larger tract which had been bought from Drury Stith of Brunswick Co. containing 800 acres. Fairfax Co records show the following, which seems to confirm the Lunenburg Co records. 18/19 August 1758 indenture between Gabriel Adams and John Adams; Fairfax Co., VA Fairfax Co. D. B. D, page 564:August 18, 1758, Gabriel Adams eldest son and heir at law of Gabriel Adams, late of the County of Fairfax and John Adams of the County of Lunenburg and Susanna his wife sell to John Dalton of Fairfax 100 acres being part of a greater tract of 515 acres granted to Gabriel Adams, father of the said Gabriel Adams and John Adams by patent Oct. 12, 1726 and by said Gabriel Adams devised to John Adams his son for life as by the last Will and Testament of Gabriel Adams proved and recorded in Fairfax Co., August 1758.Actually recorded April 1759.
