Robert requested to be "liberated" from his Henrico County Quaker community in 1710 to marry Rachel Watkins (Elizabeth's mother), who was not of that Quaker community. In 1773, he requested to be received back into his earlier community of Friends, probably after her death. Two of his children probably died prior to his death. His 1729 will name only eight of his ten children.
Sarah's brother Joseph Woodson married Elizabeth Mattox, the daughter of Quaker immigrant, John Mattox and Margaret Kent. Her sister Sarah Woodson married Joseph Parsons.
In the next generation, Joseph Woodson (son of Joseph Woodson and Elizabeth Mattox) married his cousin, Elizabeth Parsons (daughter of Sarah Woodson and Joseph Parsons): his aunt becoming his mother-in-law.
The daughter of this marriage, Judith Woodson, married Jonathan Knight, the grandson of Robert Woodson JR’s second marriage: Judith was his great-granddaughter, whereas her husband was his grandson. Their daughter was Judith Woodson Knight who married William Amis.
Elizabeth's grandfather was Robert Woodson who married Elizabeth Ferris in the 1650's. She was the daughter of immigrant Richard Ferris of Curles plantation. Robert was a wealthy planter on a large estate. His name only appeared on court records as witness to documents, and his only public service was as a Surveyor of Highways in Henrico County in 1685. He was given the title of Colonel.
Elizabeth's great grandfather, John Woodson (1586-1633) married Sarah Winston. They arrived in Jamestown in 1619 on the ship George. John was a surgeon for the company of English soldiers protecting the new colony.
