The Latons had long been established at Dalemain near Penrith as feudal tenants of their baronial neighbours, the Greystokes, but they were a family of no great distinction and no reliable pedigree can be constructed for them. Our MP’s putative father, Thomas, played a minor part in local administration: in 1395 he served as a tax collector in Cumberland, and in 1401 he was appointed as alnager there. He was alive as late as 1415, when he sat as a juror at Penrith, and William succeeded him not long afterwards. William first appears in the records in 1423 when he attested the Cumberland parliamentary indenture at Carlisle.
Laton was certainly resident in Carlisle during the 1420s. In June 1428, in a pardon of outlawry for debt, he was described as ‘of Carlisle, esquire’; and, much more significantly, he was later involved in a serious fracas there. According to an action brought in the court of common pleas by the earl of Salisbury, on 14 Dec. 1429 Sir John Skelton*, one of the leading Cumberland gentry, and his servants assaulted the earl’s men, headed by our MP and his putative brother, John Laton. Skelton’s men replied with a different story, namely that they had been standing peacefully outside their master’s house in the town when assailed by the Latons and others; the mayor of Carlisle intervened, and, if any harm came to the earl’s men, they contended it was because they resisted the mayor’s efforts to arrest them. Whatever the truth of the matter, this case provides irrefutable evidence that our MP was a trusted Neville servant.
This service explains the brief period of prominence Laton enjoyed in the early 1430s. In 1430 he was named to a commission of array headed by Salisbury; on 30 June 1433, after attesting the three previous elections, he was himself elected to represent Cumberland in Parliament; and in the following year he was named as escheator.
Laton last appears in the records on 14 May 1443, when he was a juror at the inquisition taken at Penrith on the death of Sir Christopher Moresby†. He was dead by Hilary term 1445 when his widow, Agnes, sued her putative brother-in-law, John Laton of Linstock (near Carlisle), for taking trees and underwood worth £20 and depasturing grass worth £10 at Dalemain.
However this may be, Thomas Laton was to pay a heavy price for his family’s service to Neville. On Christmas day 1452 a group of retainers of Thomas Percy, Lord Egremont, headed by Richard Bellingham*, assaulted him at Dalemain and allegedly imprisoned him until the following June. As a prisoner he petitioned Parliament for redress.
