It may be presumed that James was related to John* and Bernard Janyn*, although firm evidence is lacking. Like John, at the start of his career he held land at Ewell, and it is of interest to note that they sat together in the Parliaments of 1433 and 1435, albeit for different constituencies.
Although sometimes styled ‘yeoman’ or ‘husbandman’, James appears to have been principally engaged as a bailiff or business agent for local landowners, and early in his career he was employed as ‘King’s bailiff’ in Surrey. An indictment presented at sessions held at Guildford in January 1420 alleged that the previous Michaelmas when, on the instructions of the sheriff, James had gone to Ewell to make replevin of a certain horse, Elizabeth, wife of Robert Leversegge, and others had assaulted him and rescued the horse, and that she had cried with a loud voice ‘interficite eum et omnes eum auxiliantes’, so that James and John Janyn (then present as constable of Ewell), had feared for their lives. Nevertheless, the defendants were acquitted.
Despite these links with Sussex, it was as one of the men of Surrey that Janyn took the general oath against law-breakers in 1434.
Few details of Janyn’s landholdings survive, but he held some of his property in Croydon jointly with his first wife, and in 1445 he brought an action against John Rychard of Southwark ‘upholdester’ and his wife for breaking into his house there 13 years earlier and taking goods including silver plate worth £10. He also accused Rychard of illegally detaining ten marks, a sum noted as arrears in Rychard’s accounts as his receiver.
At the time of Cade’s rebellion in the summer of 1450 Janyn had been holding office as constable of the hundred of Wallington, and it was probably the tenure of this post which prompted him to take out a royal pardon.
