the Lancastrian party, Edward died at the Battle of Tewkesbury on 4 May 1471, while Warwick had died at the Battle of Barnet on 14 April 1471. Richard's marriage plans brought him into conflict with his brother George. John Paston's letter of 17 February 1472 makes it clear that George was not happy about the marriage but grudgingly accepted it on the basis that "he may well have my Lady his sister-in-law, but they shall part no livelihood". The reason was the inheritance Anne shared with her elder sister Isabel, whom George had married in 1469. It was not only the earldom that was at stake; Richard Neville had inherited it as a result of his marriage to Anne Beauchamp, 16th Countess of Warwick. The Countess, who was still alive, was technically the owner of the substantial Beauchamp estates, her father having left no male heirs. The Croyland Chronicle records that Richard agreed to a prenuptial contract in the following terms: "the marriage of the Duke of Gloucester with Anne before-named was to take place, and he was to have such and so much of the earl's lands as should be agreed upon between them through the mediation of arbitrators; while all the rest were to remain in the possession of the Duke of Clarence". The date of Paston's letter suggests the marriage was still being negotiated in February 1472. In order to win George's final consent to the marriage, Richard renounced most of the Earl of Warwick's land and property including the earldoms of Warwick (which the Kingmaker had held in his wife's right) and Salisbury and surrendered to George the office of Great Chamberlain of England. Richard retained Neville's forfeit estates he had already been granted in the summer of 1471: Penrith, Sheriff Hutton and Middleham, where he later established his marital household. The requisite papal dispensation was obtained dated 22 April 1472. Michael Hicks has suggested that the terms of the dispensation deliberately understated the degrees of consanguinity between the couple, and the marriage was therefore illegal on the ground of first degree consanguinity following George's marriage to Anne's sister Isabel. There would have been first-degree consanguinity if Richard had sought to marry Isabel (in case of widowhood) after she had married his brother George, but no such consanguinity applied for Anne and Richard. Richard's marriage to Anne was never declared null, and it was public to
