It may be surmised that John was related to the Kemps of Wye near Ashford in Kent, the family from which emerged his distinguished namesake John Kemp (c.1380-1454), the cardinal-archbishop, and the latter’s nephew Thomas, the bishop of London from 1448 until his death in 1489.
One possibility is that the MP was the man who lived at Robertsbridge, to the north of Battle, and established trading contacts in London and further north. In 1416 he and John Marshall of St. Neots in Huntingdonshire were bound in a statute staple at Westminster in the sum of £32 to the London grocer John Sutton. As a consequence of their failure to pay on the appointed day, orders went out for their arrest and Marshall was imprisoned by the sheriff of Huntingdonshire, although Kemp could not be found in Sussex. Later, in 1428, he relinquished any title he had to Marshall’s property in St. Neots.
New Shoreham’s poor economic circumstances encouraged the inhabitants to look to outsiders to represent them in Parliament, but even so it was rare for them to return royal servants. A suggestion that John Kemp may have been one such rests on the coincidence of the employment of a namesake by the Crown at the time of the elections to the Parliament of 1437. In July 1426 that John Kemp, a yeoman of the chamber of Henry IV’s widow, Joan of Navarre, was sent to the abbot of Winchcombe to receive a corrody at the abbey, and by the queen’s grant he subsequently held the post of keeper and porter of the south gate in the park of Havering atte Bower in Essex. This he was occupying when Parliament was summoned to meet on 21 Jan. 1437, and six months later, in July, after the dissolution and the queen’s death, he was re-granted the post by the King, who a year later gave it to him for life. Briefly, from 8 Mar. 1439 until his death, he shared it with John Boys.
