Anne Beauchamp, 16th Countess of Warwick was born July 13, 1426 at Caversham Castle in what is now Berkshire. Her father was Richard Beauchamp, 13th Earl of Warwick and her mother was his second wife, Isabel le Despenser. She married Richard Neville after being betrothed to him in 1434 (yes she was eight, he was six). They were then married in April of 1436 in a double ceremony that also included her brother Henry and Cecily Neville With her father dying then her brother Henry and his daughter Lady Anne Warwick Neville inherited the title of Warwick along with other lands through his wife. Her three older half sisters contested this. Her sister Eleanor was married to Edmund Beaufort who was closely related to the Nevilles. Richard Neville was the grandson of Joan Beaufort, Edmund’s aunt. This increased tensions between the two families. It took many years, and a Papal dispensation to eat eggs and meat during Lent to help her bear children., The couple finally had two daughters, Isabel, who married George, the Duke of Clarence(this required another Papal dispensation since Edward IV did not approve of it) and Anne who married Prince Edward first and then Richard, Duke of Gloucester who of course became Richard III. The marriage of Isabel and George caused the small family to flee England for a time during which Isabel had a stillborn son while on the ship, Calais had turned them away.
Richard Neville was often sent out of the country and there is some reason to believe that Anne went with him at least some of those times, so though the marriage was a political one they seemed content even thought Richard fathered at least one illegitimate child during the marriage.
Because of bickering over Anne’s estate Richard gave up most of the Warwick lands, which had, been held in his wife’s name and his Salisbury lands to George as well as the office of The Great Chamberlain of England. Edward inherited those lands and titles after his father was executed for treason in 1478. Anne outlived her husband, daughters and sons in laws and passed away in obscurity she was not even at the Coronation of Richard. An act of Parliament in 1474 had labeled her officially dead leaving her lands split between her sons in laws. She had petitioned Henry to receive some of her lands back with the stipulation that they would return to the Crown upon her death. She died on September 20, 1492.
