expanded his natural patrimony out of and away from Lincolnshire. The Brotherton lands were worth over £1,400 at the turn of the century, although by the time Mowbray had inherited it, he had two dowagers (the widows of his brother and father) to support out of his income, and they were themselves relatively young Thus, although he inherited a large estate in East Anglia, it has been estimated that only around half of it was under Mowbray's direct control. It may well be as a direct result of his lack of political significance in the region that even though he spent most of his career in France, on his visits home, he spent the majority of his time in London or Epworth, not the east of England. Precedence and the dukedom of Norfolk Throughout his life, Mowbray was obsessed with his "rights and privileges," even arguing with Henry V over the powers and extent of his office of Earl Marshal. His concern for establishing—and augmenting—his own authority was such that he was drawn in dispute with Richard Beauchamp, Earl of Warwick after claiming that his own earldom of Norfolk had precedence in the English peerage, and outranked that of Warwick. Mowbray first claimed precedence in 1414; the situation was not resolved until 1425 when the question was put to parliament. The House of Commons, as Archer puts it, was able to "neatly side-step" the issue by recommending that Mowbray be returned to his family dukedom. A month later, on 14 July, John Mowbray paid homage to Henry VI as the second Mowbray Duke of Norfolk, which, says Griffiths, was intended to "soothe his offended dignity and quiten the discord". Having recently fought for the Duke of Gloucester in Brabant, Mowbray relied on the duke's support against Beauchamp, who was himself known to be part of Cardinal Beaufort's clique. Family Mowbray married Lady Katherine Neville, daughter of Ralph Neville, 1st Earl of Westmorland, and had one son, John, born just before his father returned ill from France in 1415. Seventeen-year-old John Mowbray succeeded his father to the dukedom of Norfolk in October 1432, while Katherine lived for over fifty years more and married three more times. Apart from his elder brother, John Mowbray had three sisters, Elizabeth, Margaret and Isabel. Because of Thomas' treason, the sisters had to be found husbands in severely straitened circumstances. Elizabeth married Michael de la Pole,
