John de Cobham, described by Pole as a "younger son of Cobham in Kent," was the younger son of John de Cobham and Joan Septvans, and the brother of Henry Cobham, the first Baron, who died in Stoke-sub-Hamdon in 1339. The younger John Cobham married Amicia, daughter of James de Bolhay of Blackburgh-Bolhay, and inherited the manor. There were four children, James, his heir; Isabel who married John Bamfield of Poltimore; Elizabeth, to Sir Hugh Perverell, from whom the Hungerfords; and Philippa, to Nicholas Ingpen.

John de Cobham, the grandson of Henry de Cobbeham and the eldest son of another John de Cobbeham, was made constable of the Rochester Castle so early in life that he was called the "young constable," and was entrusted with the sheriffalty of Kent for four years from 44 Henry III. His seat was at Monkton in the Isle of Thanet. In 52 Henry III, 1268, he acted as a justice itinerant for Surrey and Kent, and was advanced to the bench at Westminster in Feb 1270, 54 Hen III. In 4 Edw I, he was certainly constituted a baron of the Exchequer, the mandate for which is dated 6 Jun 1276, with a salary of forty marks per annum, and there are several records showing that he continued in that office during the remained of his life. By an entry in the Year Book of Hilary, 28 Edward I, 1300, it appears that he was authorised to stay at home at his pleasure, and to come to the Exechequer and remain there when he would. This licence was no doubt granted to him in the consequence of bodily infirmity, as he died in the same year [Cal. Inquis. p.m. i. 156]. John married Joane, daughter and heir of Sir Robert de Septvans.
