[citation needed] Anthony Browne, born at Betchworth Castle,[1] was a younger son of Sir Thomas Browne and Eleanor FitzAlan, daughter of Thomas Fitzalan, third son of John de Arundel, 2nd Baron Arundel (d. 14 August 1390), and Elizabeth le Despenser (d. 10/11 April 1408).
[3][4] During the reign of Henry VII, he was Standard Bearer of England,[2] Governor of Queenborough Castle, and Constable of Calais.
In the reign of Henry VII, Lucy was noted as one who "loves not the King", and was said to be actively promoting the rival claim to the throne of her cousin Edmund de la Pole, 3rd Duke of Suffolk.
[5] This, combined with her husband's possession of a crucial fortress, was a constant worry to supporters of Henry VII: John Flamank's report of a secret conversation between several officials in Calais in 1504, on the likely sequel, if the King should die, referred to the risk that she would seize Calais and hold it in Suffolk's name.
[6] The heavy fine imposed on her in 1507, although the pretext was her late husband's neglect of duty, was very likely a warning by the Crown not to meddle in politics.
