John Paston, with some justification, claimed to be his heir; this put him in direct conflict with various major players of the time, such as the Duke of Norfolk and Sir William Yelverton.
After the death of John de Mowbray, 4th Duke of Norfolk, in 1476, and of his daughter and heir Anne in 1481, the Mowbray estates were divided between the representatives of her two co-heirs, one of whom, William, Lord Berkeley, obtained the overlordship of Pickwell and Leesthorpe for considerable time for his family: last mentioned in connection with Pickwell and Leesthorpe in 1630.

Mowbray died before 12 February 1383, aged seventeen and unmarried, and was buried at the Whitefriars in Fleet Street, London.
He was the younger son of Thomas de Mowbray, 1st Duke of Norfolk, and succeeded his elder brother Thomas as 5th Earl of Norfolk and 3rd Earl of Nottingham in 1405.

In 1425 he was restored to his father's confiscated Dukedom of Norfolk.
In 1437–8 he served a year's term as warden of the east march and in 1438 he was one of the leaders of an expedition to strengthen the defences of Calais and Guînes.
In April 1372, custody of both Thomas and his elder brother, John, was granted to Blanche Wake, a sister of their grandmother, Joan of Lancaster.
