Earl of Roden is a title in the Peerage of Ireland. It was created in 1771 for Robert Jocelyn, 2nd Viscount Jocelyn. This branch of the Jocelyn family descends from the 1st Viscount, prominent Irish lawyer and politician Robert Jocelyn, the son of Thomas Jocelyn, third son of Sir Robert Jocelyn, 1st Baronet, of Hyde Hall (see below). He notably served as Lord Chancellor of Ireland from 1739 to 1756. In 1743 he was raised to the Peerage of Ireland as Baron Newport, of Newport, and in 1755 he was further honoured when he was made Viscount Jocelyn, also in the Peerage of Ireland. He was succeeded by his son, the second Viscount. He represented Old Leighlin in the Irish House of Commons and served as Auditor-General of Ireland. In 1770 he was created Earl of Roden, of High Roding in the County of Tipperary, in the Peerage of Ireland. In 1770 he also succeeded his first cousin once removed as fifth Baronet of Hyde Hall. Lord Roden married Lady Anne Hamilton, daughter of James Hamilton, 1st Earl of Clanbrassil and sister of James Hamilton, 2nd Earl of Clanbrassil, a title which became extinct in 1798.
Lord Roden was succeeded his son, the second Earl. He sat in the Irish House of Commons for Dundalk and served as an Irish Representative Peer in the British House of Lords between 1800 and 1820. He was also a professional soldier who played a decisive, if somewhat ruthless role in suppressing the Irish Rebellion of 1798. His son, the third Earl, represented County Louth in the British House of Commons and was Auditor-General of the Exchequer in Ireland. In 1821 he was created Baron Clanbrassil, of Hyde Hall in the County of Hertford and Dundalk in the County of Louth, in the Peerage of the United Kingdom, which gave him and his descendants an automatic seat in the House of Lords. This was a revival of the Clanbrassil title held by his ancestors the Earls of Clanbrassil. Lord Roden was a leading figure in the Protestant Second Reformation. His grandson, the fourth Earl, Viscount Jocelyn's son served in the second Conservative administration of Benjamin Disraeli as a Lord-in-Waiting (government whip in the House of Lords) from 1874 to 1880.
