Nothing is known of the MP’s background, although he may have been related to the Ady family of Malmesbury.
The Seymours were prominent landowners in the vicinity of Marlborough, and owned property in the town itself. It is worthy of note that when Ady was returned by the borough to the Reading Parliament of 1453, he accompanied to the Commons Seymour’s son and heir apparent, John Seymour II*, then elected to represent the county. His tenure of the office of under bailiff of Marlborough is poorly documented, but it may be that it lasted for several years. He probably owed his initial appointment to Margaret of Anjou, or her ministers, as the Marlborough estate then formed part of the queen’s dower.
Ady appeared as a juror at inquisitions post mortem held at Salisbury in December 1458 and at Marlborough in October 1468, the latter following the death of William Zouche*, Lord Zouche.
