[6] Sir John Donne's mother, Joan Scudamore, was the granddaughter of the Welsh rebel, Owain Glyndŵr.

The earl also fell quickly into debt to the king: he failed to pay livery for his father's lands, and he was fined 2500 marks for abducting Elizabeth Trussell, whose wardship the second earl had left to Richard's half-brother Henry; he then failed to keep up the instalments laid down for the payment of the fine.

[10]As a result of these events Elizabeth Trussell's wardship and marriage again came into the hands of the King, who sold it on 29 April 1507[11] to John de Vere, 13th Earl of Oxford, and his cousin John de Vere, later 15th Earl of Oxford, for an initial payment of 1000 marks and an additional £387 18s to be paid yearly, less £20 a year for Elizabeth's maintenance.

The annual value of Elizabeth's lands had been estimated in the inquisition post mortem taken after her brother John's death at £271 12s 8d a year.

[12] Between 29 April 1507 and 4 July 1509 Elizabeth became the second wife of John de Vere, 15th Earl of Oxford, whose first wife was Christian Foderingey (born c. 1481, died before 4 November 1498), the daughter and co-heiress of Thomas Foderingey (c. 1446 – 1491) of Brockley, Suffolk, by Elizabeth Doreward (c. 1473 – 1491), daughter of William Doreward of Bocking, Essex, by whom the 15th Earl had no issue.
