For at least 20 years Ledes was employed in the service of the Mowbrays. Of uncertain origin (although his name was quite likely derived from Leeds in Yorkshire), it is unclear precisely when he joined the Mowbrays’ entourage. A man of this name was clerk of the ‘riding household’ to Thomas, Earl Marshal (d.1405), but as he was consistently described as a clerk, he may have been in clerical orders rather than a layman.
John and his kinsman William Ledes both enlisted in the Earl Marshal’s force for Henry V’s first expedition to France in 1415, only for both of them to be sent home sick from the siege of Harfleur, along with their lord.
Meanwhile, as a consequence of his offices on the Mowbray estates in Sussex, Ledes had established a place for himself in the community of the shire. In 1418 he had been commissioned to administer the goods of a kinsman and namesake, John Ledes, the vicar of Cowfold in the centre of the county.
Ledes attested the shire elections to the next Parliament, on 11 June 1433, but is not known to have taken part in any other parliamentary elections, or to have been returned to the Commons again.
Ledes’s second marriage, like his first, came about as a consequence of his connexion with the Mowbrays, for Isabel Boys, the daughter of a Lincolnshire man, was the widow of Robert Southwell, who had been Earl John’s receiver-general from 1413 to 1426, and the MP’s fellow Mowbray councillor thereafter. Isabel herself received an annuity of five marks as one of the ladies attending on the countess.
