Through marriage Foxley acquired property near the chapel of St. Clare in Hardness, a township forming part of the medieval borough of Clifton-Dartmouth-Hardness, and his holdings there and in Southtown-Dartmouth so increased over the years as eventually 1o comprise 26 messuages.
In July 1423 a commission of oyer and terminer was set up to investigate a complaint made by Thomas Gille Dartmouth that Foxley, along with two local ‘gentlemen’, Robert Hill of Churchstow and John Prideaux of Orcharton, all arrayed in a warlike manner, had assaulted him on three separate occasions, at Bigbury, Dodbrooke and Kingsbridge. It was again in association with Prideaux that, in the following year, Foxley sailed for Normandy in the retinue of Sir John Robessart, the captain of St. Sauveur le Visconte. In a petition from a Portuguese merchant dating from some time between 1426 and 1432, Foxley is described as a deputy of the admiral of England (either Thomas Beaufort or his successor from 1426, John, duke of Bedford). Although he was only once elected as parliamentary burgess for Dartmouth, he often provided securities at the elections for other representatives chosen for the borough: thus in 1421 he acted in this way for Henry Sadeler and John Burley II, in 1422, 1423, 1425 and 1431 for John Hawley II, in 1426 for John Gayncotet and William Notefield, and in 1437 for Thomas Asshenden II.
