The descendant of a Norman family which had lost its land and titles in the late sixteenth century, but had resettled and acquired an estate at Abbey Leix from the 1st duke of Ormond in the 1690s, Vesey was born at Merrion Square, Dublin in 1803 and received a second class degree in mathematics from Oxford university in 1825.
Aided by his father’s influence, Vesey was returned for Queen’s County in 1835, ‘unpledged’ but as a supporter of ‘Sir Robert Peel’s government’, defeating the sitting repeal member. He promised, somewhat vaguely, ‘to promote the welfare of Ireland’ by supporting measures designed to ‘secure the prosperity, tranquillity, and improvement’ of the country, ‘and of the Queen’s County in particular’.
Vesey, a keen yachtsman, married the daughter of the earl of Pembroke, and sister of Sidney Herbert in 1839.
He was returned unopposed again for Queen’s County in 1847, having expressed some sympathy for land reform, while being opposed to fixity of tenure.
Vesey succeeded his father as 3rd viscount de Vesci in October 1855, and was elected an Irish representative peer in January 1857.
