Beaumont was not a native of Dunwich, since he paid the customary entry fine of 6s. 8d. levied on outsiders who applied to join its freemen.
So far as is known, Beaumont took part in his first parliamentary election in late 1414 but was not involved in any succeeding elections until that of 1429 when he and John Polard* were returned. Apart from attesting the borough’s returns at the next four parliamentary elections, he also played a part in that of 1442. The Dunwich return to the Parliament of that year has not survived, but he was very likely one of the attestors, since he was a mainpernor for the newly elected Robert Cuddon*.
Beaumont began his official career not long after attesting the 1414 election, for in the following year he was one of those chosen to collect a land fine, a levy that the town authorities imposed on the inhabitants of Dunwich. In 1418 and again 11 years later, he helped to assess local taxes, and in 1421 he was one of the collectors of a dole, a fixed share of the season’s catch payable by skippers of fishing vessels to the corporation. Co-ordinating the collection of all doles became one of his responsibilities in September 1429 when, a day before his election to his first Parliament, he and Thomas James became the first two chamberlains of Dunwich. Beaumont was already a leading townsman when he became chamberlain: in mid 1425, for example, he had been among the local officers and burgesses who agreed to lease ten plots of land in All Saints’ parish (once held by Augustine Illes†, a prominent burgess of the 1330s and 1340s) to John Luke*. At the end of the same decade, the corporation asked him and other burgesses to contribute towards the cost of constructing Dunwich’s east quay. It is uncertain whether he contributed, since there is a blank after his name in the minute book’s list of potential contributors.
In June 1437, Beaumont received a pardon from the Crown.
There is no record of when Beaumont died and his exact relationship with other Beaumonts living in Dunwich in the fifteenth century is unclear. The John Beaumont who requested burial in the Dunwich parish church of St. John the Baptist in his will of 1446, was probably a relative; but it is impossible to prove that John’s son (named Henry) was the MP. Later, in a will of 1471, Thomas Beaumont also chose the same church for his burial place. Probably the man who served as a coroner of Dunwich in the late 1450s, he appointed ‘Henry Beaumont senior’ one of his executors, but it is very unlikely that this was the MP.
