Anne Bourchier, 7th Baroness Bourchier

Anne Bourchier (1517 – 28 January 1571) was the suo jure 7th Baroness Bourchier, suo jure Lady Lovayne, and Baroness Parr of Kendal. She was the first wife of William Parr, 1st Marquess of Northampton, Earl of Essex, and the sister-in-law of Catherine Parr, the sixth wife of Henry VIII of England.

She created a scandal in 1541 when she deserted her husband to elope with her lover, John Lyngfield, the prior of St. James's Church, Tanbridge, Surrey, by whom she would have several illegitimate children. In 1543, Lord Parr obtained an Act of Parliament repudiating Anne.

Lady Anne Bourchier was born in 1517, the only child of Henry Bourchier, 2nd Earl of Essex, 6th Baron Bourchier, Viscount Bourchier, 3rd Count of Eu, and Mary Say, who was a lady-in-waiting to Henry VIII's first Queen consort, Catherine of Aragon. Her paternal grandparents were Sir William Bourchier, Viscount Bourchier and Lady Anne Woodville, a younger sister of the English queen consort Elizabeth Woodville. Her maternal grandparents were Sir William Say and Elizabeth Fray. Anne was related to three queen consorts of Henry VIII; Anne Boleyn, Jane Seymour, and Catherine Howard who all shared the same great-grandmother Elizabeth Cheney.

As the only child of the last Bourchier Earl of Essex, as well as the contingent heiress of the Countess of Oxford, Anne was one of the wealthiest heiresses in England. The Bourchier wealth derived from the 14th century marriage of Sir William Bourchier to Eleanor de Lovayne (27 March 1345 – 5 October 1397), a rich heiress in her own right.
