Earl of Howth

Title in the peerage of Ireland, extinct 1909

Earl of Howth was a title in the Peerage of Ireland. It was created in 1767 for Thomas St Lawrence, 15th Baron Howth, who was elevated to Viscount St Lawrence at the same time, also in the Peerage of Ireland. The St Lawrence family descended from Christopher St Lawrence who was elevated to the Peerage of Ireland as Baron Howth in about 1425. The third and fourth Barons both served as Lord Chancellor of Ireland. The family's origins are thought to go back to Almeric Tristram, a liegeman of the Anglo-Irish knight John de Courcy, who conquered Howth in 1177. The St Lawrence family claimed significant prerogative rights as Lords of Howth over the whole peninsula, and were prepared to maintain their rights even against the English Crown.
