Conolly was a nephew of William Conolly, Speaker of the Irish House of Commons from 1715 to 1729, and was the son of Patrick Conolly, younger brother of William. William and Patrick had fled to England from Ireland in 1688, but while William had returned, Patrick remained and married Frances Hewett, one of the children of Neale Hewett and Mary Halford of Dunton Bassett, Leicestershire.[1] There were two children, William and his sister, and they grew up at Dunton Bassett until 1713 when their father died, having recently buried their mother.[2][3]

William became cursitor in the Court of Chancery (Ireland) in 1721.[4] He was elected to the Irish House of Commons for Ballyshannon at a by-election in 1727, after his uncle who had been elected in the 1727 Irish general election earlier in the year decided to continue sitting for County Londonderry instead.[5] In 1729, he succeeded to Castletown, the estate of his uncle, who was said to be the richest man in Ireland. He was appointed to the Irish Privy Council on 3 February 1730.[6] In 1733, he married Lady Anne Wentworth, daughter of Thomas Wentworth, 1st Earl of Strafford and his wife Anne Johnson;[4] and in that year he purchased Stretton Hall, Staffordshire as his seat in England, his uncle's great mansion of Castletown in Kildare still being in the hands of his widow.[7]

Castletown House

At the 1734 British general election Conolly was returned as Member of Parliament for Aldeburgh in the interest of his father-in-law Lord Strafford. Although Strafford was a Tory, Conolly considered himself "an incorrigible Whig". He voted consistently with the Government and was returned for Aldeburgh in 1741. He was classed as Old Whig in 1746. At the 1747 British general election he changed seats and was returned as MP for Petersfield instead.[4]

Conolly died on 2 January 1754 leaving an estate of £15,000 per annum. He had a son and six daughters.[4]
