Earl of Arran

Earl of Arran is a title in the Peerage of Ireland, and also in the Peerage of Scotland. The title was first created in Scotland in 1467 for Thomas Boyd, who was later attained for treason. The next creation was in 1503 for James Hamilton. In 1609, the first Marquess of Hamilton inherited the earldom. In 1643, the second Marquess was made Duke of Hamilton and received a second grant of the Earldom of Arran. At the death of the second Duke, the 1503 Earldom became dormant (i.e., it was unclaimed), while the 1643 Earldom descended along with the dukedom, with which it is still united.
