Members of the Exton family had sat in six Parliaments of the fourteenth century for the Sussex borough of Midhurst, and it is quite likely that John was a grandson of one of them, Henry Exton†. His parents were perhaps Geoffrey and Isabel Exton, who held land in the suburbs of Chichester in the reign of Richard II,
In the course of his career Exton was recorded as a witness to deeds in both Chichester and Yapton,
Exton was exercising his office as customer when returned for Chichester to Henry VI’s first Parliament, summoned in the following autumn. He had previously attested the Sussex elections held in the county court at Chichester in September 1419, and now did so again, on 15 Oct. 1422, thus participating in the choice of the shire knights whom he would accompany to the Commons.

While we can be certain about many of the details of Exton’s career up to 1431, and may confidently assume that it was he who served as a juror at inquisitions post mortem held in Chichester in the following year and in 1439,
