Obviously the death date is bad for Col.
The pedigree does seem supported:
Information obtained by Mrs. Seward from, Seventeenth Century Isle of Wight County, Virginia, by John Bennett Boddie, states: "The first of the family in Virginia was Tristram Norsworthy , who patented 200 acres in Nansemond, June 5, 1639 "towards the head of a bay behind the Ragged Islands."" On the same date he patented 150 acres near Daniel Gookin for his own personal adventure and that of his wife, Ann, and a servant. He was one of three who were the first representatives in the House of Burgesses for Upper Norfolk County in 1639. He probably died in Nansemond and the date of his death is not known.
"His eldest son was Colonel George Norsworthy, mentioned in Bacon’s Rebellion – afterwards Sheriff of Nansemond, who made his will February 1, 1700 and the same was probated in 1705. Colonel George’s children were Juliana, John, Charles, Thomas and Martha." (It is mentioned elsewhere that Colonel George married Martha Bridger.)
"Tristram Norsworthy’s other children were: William, who died in 1707; John who married Frances _____ and left a daughter; Elizabeth, who married Joseph Bridger (Will 1713); Thomas who had a wife, Susannah (no issue known) and Tristram, who married Sarah Pitt, daughter of Colonel John Pitt and his wife Olive, daughter of John Hardy. The children of Tristram, the son of Tristram were: Tristram, John, Sarah, Elizabeth, Frances, Martha and George.
George married Christian, daughter of Jeremiah Exum, one of the leading Quakers. Their children were: Christian, Elizabeth, Martha and George."
