Earl of Egmont is a title in the Peerage of Ireland that dates to 1733. Lord Egmont holds the subsidiary titles Viscount Perceval, of Kanturk in the County of Cork (created 1723), Baron Lovel and Holland, of Enmore in the County of Somerset (1762), Baron Perceval, of Burton in the County of Cork (1715), Baron Arden, of Lohort Castle in the County of Cork (1770), and Baron Arden, of Arden in the County of Warwick (1802). All are in the Peerage of Ireland except the Barony of Lovel and Holland (Peerage of Great Britain) and the 1802 Barony of Arden (Peerage of the United Kingdom).
Sir Philip's son John, grandfather of the 1st earl, was made a baronet in 1661.
The first earl of Egmont (who had been made Baron Perceval in 1715, and Viscount Perceval in 1723) is chiefly important for his connexion with the colonization of Georgia, and for his voluminous letters and writings on biography and genealogy.
His eldest son succeeded as 3rd earl, and the eldest by his second marriage (with Catherine Compton, baroness of Arden in Ireland) was in 1802 created BaronArden of the United Kingdom, a title which subsequently became merged in the Egmont earldom.
