Corbyn poses problems of identification. One candidate is the probable son and heir of Henry Corbyn, a tax collector in Staffordshire in 1380 and 1404.
Since the manor of Morfe lay only a few miles from Bridgnorth, it is very tempting to conclude that this John was the MP for the borough in 1431. Yet it is not certain that the John Corbyn of 1411 was the same man who emerges again in the records in the late 1420s. By then another John was active, the son and heir of William Corbyn of Kingswinford, very near Morfe. Both William and this John were named in 1434 among those Staffordshire men to be sworn to the general oath against peace-breakers. This younger John was active by 1430 when joint plaintiff with the prior of St. James, Dudley, in a plea of debt.
Corbyn’s parliamentary service marked the pinnacle of his modest career, even if, while an MP, he had the embarrassment of appearing in Chancery to confess that he had lost a writ of diem clausit extremum entrusted to him for delivery to the escheator of Staffordshire.
