Sir ROBERT DE ST. JOHN, 2nd but 1st surviving son and heir (k), was holding the Honor of HaInaker of the Earl of Arundel in 1242-43. He seems to have served throughout Henry's campaign in Gascony, 1253-54. In August 1257 he was going on the King's service to Wales, and he was summoned for service there, 1258, 1260 and 1263. In Oct. 1261 he was summoned to London, cum equis et armis, and all possible forces, in a matter touching the King and Crown (d). Porchester castle was committed to him, during pleasure, 12 April 1266. He is said to have married Agnes, daughter of William DE CAUNTELO. He appears to have died between 11 March 1266/7 and the 25th of that month (g). His widow (h) married, before 4 June 1271, John DE TURVILLE; they were both living in 1279.
