Hayes’s great-grandfather Challis (or Charles) Hayes of Bridgwater, Somerset, who married Deborah Holditch of Totnes, Devon, was vice-consul in Lisbon, where he was murdered by his servant in 1737. His only son Samuel, who worked as a London surgeon, married the heiress Mary Basil and so gained the valuable estate of Drumboe in the north of Ireland. As Member for Augher, 1783-90, he was an inactive opposition Whig, but he was awarded an Irish baronetcy on 27 Aug. 1789, and, presumably through his friendship with Lord Abercorn, he served as joint-governor of Donegal, 1789-1800. Following the general election of 1797 he quarrelled with one of the county Donegal Members, Alexander Montgomery, who apparently alleged that Hayes was ‘an old pintle farrier: his father was kept on charity and his mother was a Brazil mulatta slave’. A duel ensued, in which Hayes was slightly wounded twice without hitting his opponent. On his death in 1807 he was succeeded by his only son and namesake, an army officer, who also became a governor of their county. In 1803 he had married the eldest daughter of Sir Thomas Lighton, who began life as a Strabane trader but made a fortune in India, represented Tuam, 1790-7, and Carlingford, 1798-1800, as a ministerialist and ended his days a wealthy Dublin banker.
On the death of his father, who had signed the anti-Catholic petition of the Irish noblemen and gentlemen earlier that year, Hayes inherited Drumboe Castle and the baronetcy in September 1827.
Hayes signed the requisition for and was present at the abortive anti-reform meeting in county Donegal, 14 Jan. 1832, when he was described by a radical paper as a ‘brainless booby’; on the 17th, at the Protestant meeting in Dublin, he denounced the Catholic priesthood for having orchestrated the disturbances which led to its cancellation.
