By 1364 Pembridge had inherited from his father the manor of Tong and advowson of Greet in Shropshire, the manor of ‘Gyllehogh’ in Herefordshire, the manor and advowson of Aylestone in Leicestershire (which last had been in the family for over a century) and a claim to the advowson of Weston-under-Edge in Gloucestershire.
Pembridge’s status as a wealthy landowner is not reflected in his public service, which consisted of no more than five royal commissions, two of them in Shropshire, two in Oxfordshire and one on his wife’s holdings in Staffordshire. Even so, his career is not without interest. In February 1364, not long after his first marriage, he obtained the King’s licence to go on pilgrimage to Jerusalem. He travelled via Avignon where, on 21 Apr., Pope Urban V granted him and his wife plenary remission at the hour of death on condition that he went in person to the aid of the people of the Holy Land in their fight against the Turks. Pembridge’s crest (a Saracen’s head with long plaits of hair) recalls this period of his life, and he was knighted within three years of his return home. His pilgrimage and experience as a crusader no doubt contributed to his later role as a prominent member of the Palmers’ guild at Ludlow. Shortly before April 1369 he was about to sail to Aquitaine on royal business, only for his letters of protection to be revoked. However, six years later he was mustered as one of the retinue of Edward, Lord Despenser, then embarking for Brittany.
After Henry IV’s accession Pembridge was employed on two commissions of array in Oxfordshire. He seems to have had some connexion with the new King’s half-brothers, Bishop Henry Beaufort and Sir Thomas Beaufort, who were both to be remembered in his foundation of Tong college, along with the King himself and Master John Prophet, the keeper of the privy seal. Sir Fulk died on 24 May 1409. His widow and feoffees (principally William Mosse, Robert Say and Walter Swan, all parsons on the Pembridge estates) long retained possession of the Trussell inheritance (with the exception of the properties in Chester), a situation which gave rise to the violent disputes of the 1440s and beyond between the true heir, William Trussell (kinsman of Pembridge’s first wife), and the heir to his own lands, Sir Richard Vernon of Haddon (grandson of his sister Juliana).
