Although we cannot be absolutely certain about this MP’s early life and ancestry, it seems probable that he was a kinsman of the eminent Northamptonshire landowner, Sir William Thorpe† (d.c.1391), sometime keeper of the royal forest of Rockingham and knight of the body to Richard II. Sir William was in turn related to John Wittlebury, whose mainpernors at the time of his election as a shire knight for Rutland to the Parliament of 1372 included a local man named Thomas Thorpe. The latter may well have been our Member’s father; and he possibly numbered Simon Thorpe, the warden of the hospital of St. John the Evangelist and St. Anne at Oakham, among his other children. Thorpe’s own estates lay at Pilton, almost exactly half-way between Oakham and the forest of Rockingham, which lends support to the idea of this dual connexion.
Nothing is known of Thorpe’s career before his appointment, towards the end of Richard II’s reign, as a tax collector for the county of Rutland. He and his colleagues seem to have concealed part of these revenues, and in October 1402 he was ordered by the Crown to surrender the £20 which still remained in his hands. A Thomas Thorpe of Northamptonshire and a namesake described as living near Leicestershire appear at about this time in the records of central government, but it is now impossible to tell if these references (all of which concern the offer of bail of sureties for other people) are to the subject of this biography.
No more is heard of Thorpe until June 1409, when he witnessed a conveyance of property in Whipsnade, Bedfordshire. He attended the elections held at Oakham in April 1413 to the first Parliament of Henry V’s reign when his old friend, John Pensax, was successful; and he once again witnessed the indenture of return of shire knights made in November 1422, just after the accession of Henry VI. Sir Henry Pleasington, who was chosen on the last occasion together with his father-in-law, Roger Flore, the Speaker, may well have been another of our Member’s kinsmen, since he was certainly related to Sir William Thorpe. We do not know if Thomas Thorpe himself left any immediate heirs, or, indeed, if he ever married, although there is a strong possibility that he died shortly after his last appearance in the county court.
