The Eytons of Leeswood claimed descent from Kynfrig Evell, a twelfth century Welsh nobleman, adopting their English surname in the early Tudor period, when the head of the family married into the Eytons of Eyton Hall near Wrexham in eastern Denbighshire.
Although he had just succeeded as head of his family when returned to Parliament in 1614, Eyton was not an obvious choice for the Flint Boroughs seat. Even by local standards, his inheritance cannot have been very substantial: his father was rated at a mere 30s. in lands for the subsidies of 1597 and 1601 and was not appointed to the commission of the peace until 1610.
Eyton served as a magistrate from 1618 and was pricked as sheriff in 1638, after (Sir) Richard Wynn* secured exemption for Sir Thomas Mostyn. He was fortunate that the Ship Money levy for that year was substantially less than previous demands, and while the £216 required came in slowly, it was collected without incident, although £60 went missing while en route to London.
