Earl of Ulster

The title of Earl of Ulster has been created six times in the Peerage of Ireland and twice in the Peerage of the United Kingdom. Since 1928, the title has been held by the Duke of Gloucester and is used as a courtesy title by the Duke's eldest son, currently Alexander Windsor, Earl of Ulster. The wife of the Earl of Ulster is known as the Countess of Ulster. Ulster, one of the four traditional provinces of Ireland, consists of nine counties: six of these make up Northern Ireland; the remainder are in the Republic of Ireland. Provided by Wikipedia
