Mary Burden

While in England, Fleete married Sarah Burden, a widow and brought her to Virginia. They had one son, Henry Fleete." (p.66) He left his widow so well provided for that she could twice remarry respectably, first Col. John Walker, a member of the King's Council and later, Dr. John Stone. She could also send for her daughter in England, and bequeath young Henry (not yet of age) a deed of gift to all his father's lands. Even after remarriage she always signed her name on legal documents as "Widow Fleete". (pp.72-3)

"Adventurers of Purse and Person" Vol. 1, (p.972) has more: "Rather late in life Henry Fleete married a widow, Sarah ( ) Burden, who had a young daughter Mary Burden. Sarah married third, bef 28 Oct 1661, Col. John Walker of Gloucester County (died 1668/9) and had two daughters by him, Sarah Walker and Hester Walker, and married fourth, by 2 Nov 1672, Col John Stone, by whom she has no children. As Sarah Walker she left a will, 28 Jan 1668/9 - 29 Dec 1679." A footnote says: She named her son Henry, daughters Mary Burden,Sarah Walker and Hester Walker and Colonel Walker's six daughters.

p 17 Sarah, widow of Henry FLEET, had a "natural" daughter called Mary BURDEN. Col. WALKER provided a legacy, for Mary BURDEN when he married Sarah FLEET, indicating that he was the father of Sarahs illegitimate daughter Mary BURDEN.
