Biography

KATHERINE de VERE (c.1541-January 17, 1600)

Katherine de Vere was the daughter of John de Vere, 16th earl of Oxford (1512-August 3, 1562) and his first wife, Dorothy Neville (1515-c. January 1548). On February 1, 1548, while still a child, she was promised in marriage to the duke of Somerset's son, Henry Seymour, age seven. This marriage contract was cancelled after Somerset's execution. Katherine instead married Edward, 3rd baron Windsor (1532-January 24, 1575) and was the mother of Frederick, 4th baron (February 2, 1559-December 24, 1585), Henry, 5th baron (August 10, 1562-April 6, 1605), Andrew (d.1598+), Edward (d.1598+), William (1566-before 1598), Catherine (c.1567-December 15, 1640), and Margaret (d.1598+). On her father’s death, Katherine brought suit against her half brother, claiming that his mother’s marriage to her father had not been valid because there had been a precontract between her father and Katherine’s lady-in-waiting, Dorothy Fosser. Her will, written February 14, 1598, can be found at Oxford-Shakespeare.com. She died at Hewell in Worcestershire and was buried at Tardebigge. Portraits: alone, 1567; with her family, 1568; both by the Master of the Countess of Warwick
