Gore, Sir Ralph (1675?–1733), 4th baronet, speaker of the Irish house of commons, was elder son of Sir William Gore, 3rd baronet, MP for Banagher 1661–66, and his wife Hannah, and was born at Manorhamilton, Co. Leitrim, which his mother had inherited from her father, James Hamilton. Her uncle was Gustavus Hamilton (qv), 1st Lord Boyne. Ralph Gore entered TCD in 1693; he may have been admitted to the King's Inns in 1717. He succeeded his father in his title and estates c.1703, and seems to have been the first of his family to live in Fermanagh, where they had over 7,000 acres. He built a house on the island of Ballymacmanus in Lough Erne, greatly beautified the place, and renamed it Belleisle. He was high sheriff of Leitrim (1710) and MP for Donegal borough (1703–13); the Dublin alderman Ralph Gore who was elected lord mayor in 1711 was presumably another man of the same name. In 1713 Sir Ralph Gore's election for Co. Donegal was supported by his kinsman, James Hamilton (qv), 6th earl of Abercorn, though Gore was a whig and Abercorn a tory. Gore was MP for Co. Donegal in two parliaments (1713–14, 1715–27), and MP for Clogher 1727–33. He supported the powerful speaker of the house of commons, William Conolly (qv); opponents described him as Conolly's ‘creature’, and it was with Conolly's backing that Gore became chancellor of the exchequer in 1717; he was sworn of the privy council in 1714 and 1727, and when Conolly resigned (1729), Gore replaced him as speaker. Conolly's grouping in parliament apparently hoped that his hegemony could be perpetuated under his successors in office, Gore and Marmaduke Coghill (qv); but though Gore had some influence over his many kinsmen and clients, and as lord justice in 1730 and 1732, he had not equalled the supremacy of his mentor when he became ill in January 1733. He died 23 February 1733, and was buried in Christ Church cathedral, Dublin.
He married first Elizabeth, daughter of Sir Robert Colville (qv) of Newtown (Newtownards), Co. Down. The marriage licence was issued in 1705; there were two daughters, one of whom married John Donnellan, MP, and the other married Anthony Malone (qv). After his first wife's death, he married Elizabeth (d. 1741), only daughter of St George Ashe (qv); they had three sons and four daughters. Two of his sons became MPs, and two of their sisters married MPs; one son married Catherine Conolly, sister of Thomas Conolly (qv).
