Overview
Mary de Vere ( – 24 June 1624) was a 16th-century English noblewoman. The daughter of John de Vere, 16th Earl of Oxford, and his second wife Margery Golding, she married Peregrine Bertie, 13th Baron Willoughby de Eresby. The couple lived with their seven children in Grimsthorpe Castle in Lincolnshire. Following Bertie's death, Lady Willoughby married Sir Eustace Hart. She died on about 24 June 1624.
Early life and family
No records exist for the date or place of birth of Mary, second child of John de Vere and his second wife, Margery Golding. She was born in late 1554 at the earliest, according to Professor Alan H. Nelson, her brother's biographer. He notes there's no mention of a pregnancy or sibling to Edward in the codicil to her father's will dated 28 Jan 1554. Mary's birthplace might thus be Hedingham Castle, Veer House in London, or one of her father's ten additional vast Essex estates. Mary's half-uncle was Arthur Golding, a translator of the classics and John Calvin. Shakespeare relied on Golding's translation of Ovid's Metamorphosis as a frequent source for his long poems and plays. Mary's brother Edward de Vere, 17th Earl of Oxford, married Anne Cecil, daughter of William Cecil, Lord Burghley, and the translator Mildred Cooke.
On 31 August 1562, Mary's father died. Twelve-year-old Edward de Vere became the 17th Earl of Oxford and was moved into William Cecil's household. Mary was probably seven or younger and thus likely remained with her mother, Margery Golding, who soon married Sir Charles Tyrrel. Golding died in 1569.
Marriages and issue
Mary was probably 21 when she accepted the proposal of Peregrine Bertie, 13th Baron Willoughby de Eresby. Two powerful women initially prevented the marriage: Queen Elizabeth and Bertie's mother, Katherine Brandon, Duchess of Suffolk. Their objection was Edward de Vere's abuse of his wife Anne Cecil. Oxford was in France when Anne became pregnant with their first child, and he initially responded with enthusiasm, sending Anne lavish presents. Then her father failed to stop an Oxford cousin from being executed, and de Vere set out to ruin Anne in retaliation. On his return in 1575, he publicly accused her of adultery, refused to live with her for five years, demanded she be banished from court, and declared their daughter a bastard. William Cecil eventually interceded, and Mary's marriage proceeded. Cracroft's Peerage gives their date of marriage as between December 1577 and 12 March 1578.
