Earl of Kinnoull

Earl of Kinnoull (sometimes spelled Earl of Kinnoul) is a title in the Peerage of Scotland. It was created in 1633 for George Hay, 1st Viscount of Dupplin. Other associated titles are: Viscount Dupplin and Lord Hay of Kinfauns (1627) and Baron Hay of Pedwardine (1711). The former two are in the Peerage of Scotland, while the third is in the Peerage of Great Britain. The title of Viscount Dupplin is the courtesy title for the Earl's eldest son and heir.

History
The Hay clan descends from Norman-born knight Guillaume de la Haye, who was pincerna (cup bearer or butler) to Malcolm IV and William the Lion. Charles I advanced Sir George Hay to the peerage on 4 May 1627 under the titles of Baron Hay, of Kinfauns and Viscount Dupplin. On 25 May 1633, Hay was created the Earl of Kinnoull by King Charles I.

The Hay family share a common ancestor with the Earls of Erroll. Gilbert de la Hay (died April 1333), ancestor of the Earls of Erroll, was the older brother of William de la Hay, ancestor of the Earls of Kinnoull. In 1251, William received a charter of two carucates of land from his brother, which was confirmed by King Alexander III.

In 1711, the unofficial prime minister Robert Harley, 1st Earl of Oxford and Earl Mortimer, made his son-in-law Viscount Dupplin Baron Hay of Pedwardine in the Peerage of the United Kingdom.

The family seat is Dupplin Castle, just outside Perth, Scotland.
