“ The title of Charlemont descended from Sir Toby Caulfeild (1565–1627) of Oxfordshire, England, who was given lands in Ireland, and created Baron Charlemont (the name of a fort on the Blackwater) , for his services to King James I. in 1620, and the 1st viscount was the 5th baron (d. 1671) , who was advanced by Charles II. Lord Charlemont is historically interesting for his political connexion with Flood and Grattan; he was a cultivated man with literary and artistic tastes, and both in Dublin and in London his amiable character gave him considerable social influence. ”
