More may be added to the earlier biography.
Mayne’s contacts with the Fitzalan earls of Arundel dated back at least to the days of Earl John. Their relations were not, however, invariably cordial: in the summer of 1430 the earl was suing Richard and his kinsman John Mayne in the King’s bench for a breach of the statute of forgery.
In June 1437 Mayne, then serving as Bishop Stafford’s bailiff of the episcopal liberty in Wells, fell victim to an attack by a mob of some 40 townsmen, who sought to prevent him from executing his office in taking sureties of the peace from two local men.
