Mary White

She was probably born no earlier than 1565 but not later than 1570 (she was not yet married when her father died in 1585, and arrangements weren't finalized until c. 1587). And she certainly lived past 1593 and probably to circa 1600 or so. Not only was Richard White "IV" her son, so were Thomas "Blacklow" White and Jerome White, OSB, and she also had a daughter Mary who was married to Phillip Waldegrave. The Visitation of Essex for 1612 claims there was one more son, born 1608, but gives no other particulars.

From "A Who's Who of Tudor Women":

MARY PLOWDEN (d.1593+) Mary Plowden was the daughter of Edmund Plowden of Plowden, Shropshire, Shiplake, Oxfordshire, and Burghfield, Berkshire (1519/20-1585) and Catherine Sheldon (d. before 1585). The History of Parliament describes her father as the "greatest and most honest lawyer of his day."

At his death, Plowden made provision for Mary's dowry but did not specify an amount. He left her in the care of three women, Mary's maternal aunt, Philippa, widow of Anthony Pollard (d.1577), Mrs. Englefield—probably Margaret Fitton (1529-August 29, 1612) the mother of his former ward, Francis Englefield—and Mary's older sister, Anne, wife of Francis Perkins.

Mary's brother Edmund, who died unmarried in August 1587, specified the amount of her dowry at £1000.

She married Richard White of Hutton, Essex (1560-August 19, 1614). Their second son, Thomas White, alias Blacklow (1593-July 6, 1676), became famous as a secular priest. Their other children were probably Richard and Mary [and Jerome]. One genealogy also lists a Lydia (b.1587). Most give a date for Mary Plowden's marriage that is much too early, given the documentation relating to her dowry.
