Baron Holmes was a title that was created twice in the Peerage of Ireland. The first creation came on 11 September 1760 when the politician Thomas Holmes was made Baron Holmes, of Kilmallock in the County of Limerick. The title became extinct on his death on 21 July 1764. The second creation came on 6 November 1797 when Leonard Holmes was made Baron Holmes, of Kilmallock in the County of Limerick. He was the nephew of the first Baron of the 1760 creation. The title became extinct on his death on 18 January 1804. Barons Holmes, first creation (1760)

Leonard Holmes, 1st Baron Holmes ( – 18 January 1804). Born Leonard Troughear, he was the son of Thomas Troughear and Elizabeth Holmes, daughter of Henry Holmes and sister of Thomas Holmes, 1st Baron Holmes. He was a clergyman. On succeeding to his uncle Lord Holmes's estates he assumed the surname of Holmes in lieu of his patronymic. In 1797, the barony held by his uncle was also revived when Holmes was raised to the Peerage of Ireland as Baron Holmes, of Kilmallock in the County of Limerick. Lord Holmes married Elizabeth Tyrrell. They had one daughter, The Honourable Catherine Holmes, who married Edward Rushworth and had several children by him. Lord Holmes died in January 1804. As he had no sons the barony died with him. Lady Holmes died in 1810. Genealogy
