Davy’s descent cannot be established with absolute certainty, but he probably came from a family of middling wealth resident in Leechwell Street outside the west gate of Totnes.
It is not certain how Davy’s first return for the borough of Barnstaple (where he is not known to have had any connexions or property) came about. It is possible that it resulted from the inability of the mayor, Walter Hayne*, to find a local candidate willing to travel with him to the provincial backwater of Bury St. Edmunds. If so, it is possible that it was Thomas Courtenay, earl of Devon (with whom Davy may already have been connected by this date), who promoted his candidature. No such noble patronage was presumably necessary in 1455 when Davy was returned by his neighbours at Totnes.
Nothing is known of Davy’s activities in the Commons, but as he was not implicated in the acts of violence committed by the Courtenay retinue throughout the summer and autumn of 1455, it may be that he did indeed remain at Westminster for most of the first two sessions. However, within four days of the Christmas prorogation on 13 Dec. 1455 he was back in the south-west among an armed band of Courtenay retainers who raided and pillaged the residence of the earl’s enemy William, Lord Bonville*, at Shute and carried off the valuable furnishings.
Little else is known of Davy’s career, but he was evidently still alive in the autumn of 1462, when one Robert William appeared in the court of common pleas and sued him for a debt of 40s. resulting from the purchase of certain canvas cloth in January 1461, and a loan made at the same time.
