Hayne’s parentage is obscure, but his family may have originated in Pilton, to the north-west of Barnstaple, where he owned property.
Hayne’s career was essentially a local one, and he is not known to have ever held office under the Crown, but he evidently rose to some prominence among the merchants of Barnstaple, and from the later 1430s served several terms in local office. In the mid 1440s his neighbours elected him mayor of the borough, and he was serving in this office in December 1446, when writs were issued from Chancery summoning Parliament to assemble at Cambridge the following February. Before an election could be held, the meeting place of Parliament was changed to Bury St. Edmunds by fresh writs of 20 Jan., and Hayne, like many mayors of remote boroughs, faced an acute problem. When Parliament met at Westminster, the proximity of the markets of London and the central law courts inclined individuals to offer themselves as MPs, whereas the provincial backwater of Suffolk represented a far less appealing destination. It may thus have been an inability to find anyone prepared to travel to East Anglia, rather than a conscious breach of electoral convention, which prompted Hayne to return himself alongside the comparatively obscure Totnes yeoman William Davy alias atte Lake*.
Although evidently respected by the Barnstaple merchant community, Hayne did not enjoy universal popularity among his neighbours. In 1437 he and his brother-in-law, John Holman, had been accused by John Coffyn of felling and stealing his timber to a value of £40,
The date of Hayne’s death has not been established, but he may have died, probably without surviving issue, before 1459, when his brother-in-law John Holman (who two years later became vicar of Barnstaple), arranged for his paternal family lands, including those originally settled on Walter’s wife, to be used for the foundation of a chantry. Hayne’s own property in Pilton went to the leper hospital of St. Margaret there, to provide for prayers for his soul, as well as those of his wife, their children, parents and benefactors.
