John was born into one of the leading families of Lincoln.
As with most of Lincoln’s MPs during the Lancastrian period, the paucity of surviving city records makes it difficult to put any flesh on the dry bones of an administrative career. Ratheby probably maintained his father’s trading interests – in 1432 a merchant from Grantham was pardoned for not answering him on a plea of debt, and in 1440 he himself was defendant in an action of trespass sued by a London tailor – but he also had landed interests, for he was styled ‘gentleman’ rather than ‘merchant’.
Little can be discovered concerning Ratheby’s property holdings in the city, but these must have been considerable, for through his mother he inherited the lands once of Robert Appleby. At his death, Appleby had owned property in the parishes of St. Peter at Arches, St. Peter in Wigford, St. Lawrence and elsewhere in the city, and in his will of 1407 he settled the reversion, after the deaths of his widow and others assigned life interests, on John’s parents and the issue of John’s mother.
Ratheby was involved in two unusual legal actions. According to an action brought in King’s bench, on 8 Sept. 1433 he joined three men of Boston in abducting a prisoner of war from the custody of John, son of John Bruyn*, at Bridgnorth in Shropshire. In Trinity and Michaelmas terms 1436 Ratheby troubled to appear personally to answer, but the plaintiff abandoned his suit and there is no evidence to give the alleged abduction a context.
