Lord Rollo, of Duncrub in the County of Perth, is a title in the Peerage of Scotland. It was created on 10 January 1651 for Sir Andrew Rollo. His great-great-grandson, the fifth Lord, was a Brigadier-General in the Army and fought in North America during the Seven Years' War. He died without surviving male issue and was succeeded by his younger brother, the sixth Lord. His grandson, the eighth Lord, sat in the House of Lords as a Scottish Representative Peer from 1841 to 1846. His son, the ninth Lord, was a Scottish Representative Peer from 1847 to 1852. His son, the tenth Lord, sat in the House of Lords as a Scottish Representative Peer from 1860 to 1868. On 29 June 1869 he was created Baron Dunning, of Dunning and Pitcairns in the County of Perth, in the Peerage of the United Kingdom. This title gave the Lords an automatic seat in the House of Lords. As of 2017[update] the titles are held by the tenth Lord's great-great-grandson, the fourteenth Lord, who succeeded his father in 1997. He is the hereditary Clan Chief of Clan Rollo.
The family seat was Duncrub Castle, near Dunning, Perthshire.
