There have been ten baronetcies created for persons with the surname Mackenzie, seven in the Baronetage of Nova Scotia and three in the Baronetage of the United Kingdom. Four of the creations are extant as of 2010.
The Mackenzie Baronetcy, of Tarbat in the County of Ross, was created in the Baronetage of Nova Scotia on 21 May 1628 for John Mackenzie. His son, the second Baronet, was created Earl of Cromarty in 1703. He resigned the baronetcy in favour of his younger son Kenneth, who was created a baronet in the Baronetage of Nova Scotia on 29 April 1704, with remainder to his heirs male whatsoever and with the precedence of 1628. The third Baronet was one of the Scottish representatives to the 1st Parliament of Great Britain and later represented Cromartyshire. The fourth Baronet was Member of Parliament for Inverness Burghs and Cromartyshire. In 1744 he succeeded to the Mackenzie Baronetcy of Roystoun on the death of his uncle Sir James Mackenzie, 1st Baronet, of Roystoun (see below). On the death of the fifth/third Baronet in 1763 the next heir was under attainder and the baronetcies were consequently forfeited.
The Mackenzie Baronetcy, of Coul in the County of Ross, was created in the Baronetage of Nova Scotia on 16 October 1673 for Kenneth Mackenzie. His father Alexander Mackenzie of Coul was the illegitimate son of Colin Cam Mackenzie, 11th of Kintail, and half-brother of Kenneth Mackenzie, 1st Lord Mackenzie of Kintail, ancestor of the Earls of Seaforth, and of Sir Roderick Mackenzie, ancestor of the Earls of Cromarty. The third Baronet was involved in the Jacobite Rising of 1715. He was attainted with the baronetcy forfeited.
However, the baronetcy has since been assumed by descendants of the brother of the third Baronet. It is claimed that the attainder did not include collateral branches. The tenth Baronet was Premier of Queensland. The Right Reverend Henry Mackenzie, Suffragan Bishop of Nottingham, was the youngest son of John Mackenzie, third in descent from Simon Mackenzie, second son of the first Baronet. The presumed thirteenth and present Baronet has not successfully proven his succession and is therefore not on the Official Roll of the Baronetage. For more information, follow this link.
