Perthshire residence of the Murray Dukes of Atholl and a frequent point of correspondence in the administration of their Manx interests.

The Atholl Papers show Manx business moving regularly between the Island and Dunkeld after Revestment. In 1775 the Duke discussed the transfer to him of his mother's remaining rights connected with the Isle of Mann and instructed that a cannon and a picture from the Island should be sent to Dunkeld when an opportunity arose.

John Quayle and William Callow continued to report to the Duke on rents, mines, boons, church property and appointments. A letter of June 1777 sent from Dunkeld shows the Duke dealing with the assignment of Manx mines and the ruined chancel of Malew. He admitted that he was “too little acquainted with the affairs of the Isle of Mann” to determine the latter matter himself and instructed his agents to obtain advice from someone familiar with Manx law and custom.

Dunkeld was also the place from which the Atholls addressed the proposed sale of the Island. On 18 July 1764 the Duke wrote to Daniel Mylrea denying reports that he and the Duchess were about to sell Mann and stating that no approach had then been made by government. A surviving memorandum copied at Dunkeld in 1759 also set out the Duke's earlier response to Treasury approaches, insisting that any transfer to the Crown would leave the Manx inhabitants with their own constitution, laws, administration of justice and internal trade.

The place remained part of Manx government correspondence after the sale. In December 1803 the fourth Duke wrote from Dunkeld proposing to resign as Governor-in-Chief of the Isle of Mann in favour of his brother Lord Henry Murray.
