Following the death of Sir William Cheyne in 1345, almost all his estates passed to his eldest son,
Edmund
†, Ralph’s half-brother. Ralph, then aged eight, inherited only the manor of Tothill in Lincolnshire, which had belonged to his mother’s family, the Gorges. Edmund served as warden of the Channel Islands from 1358 until 1367, and it was probably there that Ralph spent his youth, for it was as ‘of Jersey’ that in 1359 he acted as a surety for the custodian of the priory of Vale in Guernsey, and later, in 1368 and 1370, when in England, he nominated attorneys to act on his behalf in the Islands.
In 1368 Cheyne married one of the heirs of Sir John Pavely’s estates in Wiltshire. These had already been partitioned, but Cheyne objected that his wife’s share was worth less than that allotted to her nieces, the daughters of her sister Alice, wife of
Sir John St. Loe
†, so a second partition was made giving the Cheynes moieties of the hundred of Westbury and the manor of Brooke, a half-share of the profits of the view of frankpledge and the market and fair at Westbury, the hamlets of Ditteridge and Hawkeridge and £6 of yearly rent from the manor of Westbury. Cheyne’s wife later inherited a moiety of the manor of Hilperton from a kinsman.
Cheyne’s first post of any importance came about through his relationship with the influential Sir Robert Assheton of Pitney, Somerset, a cousin on his mother’s side. Assheton held office as justiciar of Ireland, and when he left the province in September 1373 he named Cheyne as his deputy during his absence. This connexion with Assheton (who was treasurer of Exchequer from 1375 to 1377) long continued, and by April 1381 Cheyne was supplying his place as warden of the Cinque Ports and constable of Dover castle, positions he may well have retained until Assheton’s death in January 1384. Cheyne and (Sir) Maurice Russell were then found to be Assheton’s heirs to the manors of Litton and Bradpole in Dorset, and after a lawsuit to obtain possession of Litton they divided it between themselves. In the meantime in the summer of 1383 Cheyne had been appointed chancellor of Ireland and had crossed to the province again, this time with the new lieutenant, Sir Philip Courtenay. Although he was chancellor for not much longer than a year, handing over the great seal to his successor in Dublin on 8 Nov. 1384, Cheyne was handsomely rewarded, being granted two weeks later, for a down payment of £160, the custody of estates in Wexford during the minority of the earl of Pembroke.
The 1390s were a quieter period for Cheyne: he was appointed to but few commissions, and acted only twice as a mainpernor (in 1390 for Sir Robert Corbet and in 1391 for
Sir Thomas de la Mare
†).
