Although he came from one of the borough’s leading families, John Dalton is, on the available evidence, one of the more obscure of Newcastle’s MPs in Henry VI’s Parliaments. His father, aside from representing the borough in the Parliament of May 1413, served as sheriff and customs collector there, and attested as many as seven of the borough’s parliamentary elections. By contrast, John is not recorded as either attestor or borough office-holder.
Despite Dalton’s apparent inactivity in public affairs, his marriage gave him status enough to secure election for his native town to the Parliament of February 1449, but his election did not herald a new period of activity. His only recorded administrative activity thereafter is his appointment to a commission of gaol delivery in December 1454. What is known of his private activities relates to Kingston-upon-Hull rather than Newcastle. His mother had, in the late 1420s, married the wealthy Hull merchant, John Bedford†, and after his death in 1451, Dalton, as one of his executors, took a part in the foundation of a chantry in his memory in the Hull church of Holy Trinity.
