The first formal claim to the Chiefship is one by a Captain Murdoch Mackenzie, "of London," who claimed "the titles, honours, and dignities of Earl of Seaforth and Baron Mackenzie of Kintail," in virtue of a pretended descent and pedigree from the Hon. John Mackenzie of Assynt, second son of Kenneth Mor, third Earl of Seaforth. This pedigree and claim is before us. According to that document the Hon. John Mackenzie of Assynt had a son "Murdoch Mackenzie of Lochbroom, who, having shown a disposition of enterprise like his kinsman Earl William, left his native parish in 1729 or 1730, first for Aberdeen and afterwards for Northumberland, where, in consequence of the unsettled state of Scotland, he resided with his family." This Murdoch had a son, John Mackenzie, "born in Beadnall, parish of Bamborough, county of Northumberland, in 1738, who married Miss Isabella Davidson in 1762, and died in 1780, in his forty-second year." John had a son, "Captain Murdoch Mackenzie, the claimant, who was born at Beadnall, county of Northumberland, in 1763, and married in 1781, Miss Eleanor Brown of the same place, and has issue. He commanded the ship Essex, transport 81, of London, during the late war. Being desirous to see his clan in the North, in 1790 he visited the late Francis Lord Seaforth, who in the true spirit of Scotch sincerity, hospitality, and nobility received him with demonstrations of pleasure. After talking over family matters his Lordship candidly said that Captain Murdoch ought to have been the peer in point of primogeniture." A short account of the family accompanies the pedigree and claim, which concludes in these terms - "In consequence of the death of the last peer it has been discovered in Scotland that the titles and family estates have devolved upon Captain Murdoch Mackenzie of London. This gentleman is naturally anxious to establish his rights, but being unable to prosecute so important a claim without the aid of sufficient funds he has been advised to solicit the aid of some individuals whose public spirit and liberal feelings may prompt them to assist him on the principle that such timely assistance and support will be gratefully and liberally rewarded. Captain Mackenzie hereby offers to give his bond for L300 (or more if required) for every L100 that may be lent him to prosecute his claim - the same to become due and payable within three months after he shall have recovered his titles and estates." The result of this appeal has not been ascertained, but it is certain that Captain Murdoch Mackenzie did not succeed in establishing any claim either to the titles or estates of the House of Kintail and Seaforth.
