Everdon was a lawyer from a family of middling gentry, long established at Bushbury near Wolverhampton.
Such connexions were important to a young lawyer, but, without property of his own, Everdon could not expect to play a part in county administration. His father was still alive in Trinity term 1445, when father and son joined together, as feoffees, in making a jointure settlement upon their neighbour, Thomas Swynnerton of Hilton, and Elizabeth, his wife.
Most of the evidence of Everdon’s activities in the 1450s shows him busy promoting the concerns of the earl of Wiltshire and Humphrey Stafford III, who succeeded his father in 1450. By Trinity term 1450 he was one of the earl’s feoffees in a Warwickshire manor; and in May 1454 he joined with another of these feoffees, Henry Filongley*, in offering mainprise for the earl in an Exchequer grant.
Everdon’s high standing in the late 1450s is reflected in his appointment to the quorum of the Staffordshire bench in 1456 and to that of Worcestershire two years later.
During the crisis years of 1459-61 Everdon had strong reasons to favour the house of Lancaster: he was of the affinity of the militant Lancastrian earl of Wiltshire and he was a friend of Henry VI’s old servant, John Hampton.
Everdon was probably seen as politically neutral, a conclusion consistent with his appointment to a commission of array in March 1470 and his retention on the Worcestershire bench during the Readeption.
Everdon last appears in an active role early in 1471 when he acted in a fine for Richard, son and heir of another local lawyer, Richard Blike*.
