Earl of Limerick is a title that has been created twice in the Peerage of Ireland, associated first with the Dongan family, then with the Pery family. It should not be confused with the title Viscount of the City of Limerick (usually shortened to Viscount of Limerick, or Lord Limerick) held by the Hamilton family also Earls of Clanbrassil.
The earldom was created for the first time in 1686 for Sir William Dongan, 4th Baronet, with remainder, failing male issue of his own, to his brothers Robert, Michael and Thomas and the heirs male of their bodies. He had been made Viscount Dungan, of Clane in the County of Kildare in 1661, also in the Peerage of Ireland and with similar remainder. His only son Walter Dungan, Viscount Dungan, was killed at the Battle of the Boyne and Lord Limerick was succeeded according to the special remainders (and normally in the baronetcy) by his brother Thomas Dongan, the second Earl. He was Governor of New York from 1683 to 1688. All three titles became extinct on his death in 1715. The Dungan Baronetcy, of Castletown in the County of Kildare, was created in the Baronetage of Ireland in 1623 for Walter Dungan. He was the eldest son of John Dongan or Dungan (died 1592), originally of Fishamble Street, Dublin and his wife Margaret Forster. John Dongan was a civil servant who became a figure of some importance in the Irish Government, and was rich enough in later life to acquire substantial estates in County Kildare.
The title was created for the second time in 1803 in favour of Edmund Pery, 1st Viscount Limerick. He was the son of the Right Reverend William Pery, Bishop of Limerick from 1784 to 1794. In 1790 the latter was raised to the Peerage of Ireland as Baron Glentworth, of Mallow in the County of Cork. He was succeeded by his only son, the second Baron. He represented Limerick City in the Irish House of Commons and was a supporter of the Union with Great Britain. On 29 December 1800 he was created Viscount Limerick, of the City of Limerick, and on 11 February 1803, he was further honoured when he was made Earl of Limerick, of the County of Limerick. Both titles were in the Peerage of Ireland. Lord Limerick sat in the House of Lords as one of the 28 original Irish Representative Peers from 1800 to 1844. In 1815 he was also created Baron Foxford, of Stackpole Court in the County of Limerick, in the Peerage of the United Kingdom, giving him a permanent seat in the Lords. His great-grandson, the third Earl, was a Conservative and Unionist politician and served as Captain of the Yeomen of the Guard from 1889 to 1892 and from 1895 to 1896. He was succeeded by his eldest son, the fourth Earl. He died without surviving male issue and was succeeded by his half-brother, the fifth Earl. He was a soldier and also served as President of the Medical Research Council between 1952 and 1960. His eldest son, the sixth Earl, was a successful businessman. Lord Limerick also served as Under-Secretary of State of Trade from 1972 to 1974 in the Conservative administration of Edward Heath. As of 2014, the titles are held by his son, the seventh Earl, who succeeded in 2003.
Another member of the Pery family was Edmund Pery, 1st Viscount Pery, Speaker of the Irish House of Commons from 1771 to 1785. He was the elder brother of the first Baron Glentworth.
Some heirs to the earldom have used the title Viscount Glentworth as a courtesy title (instead of the "real" title of Baron Glentworth), although there is no such peerage.
The family seat was Dromore Castle, near Pallaskenry, County Limerick.
The heir apparent is the present holder's son Felix Edmund Pery, Viscount Glentworth (born 1991).
