Colquhoun Baronets

There have been two Baronetcies created for members of the Colquhoun family, one in the Baronetage of Nova Scotia and one in the Baronetage of Great Britain. Both titles are extant as of 2008.

The Colquhoun, later Grant, later Grant-Ogilvy, later Ogilvy-Grant, later Grant of Grant Baronetcy, of Colquhoun in the County of Dumbarton, was created in the Baronetage of Nova Scotia on 30 August 1625 for John Colquhoun. On 30 March 1704 Sir Humphrey Colquhoun, the fifth Baronet, resigned his baronetcy to the Crown and on 29 April of the same year was granted a new patent, with the old precedence, but with remainder to his son-in-law James Grant and the heirs male of his marriage with Sir Humphrey's daughter. James Grant succeeded as sixth Baronet according to the new patent and assumed the surname of Colquhoun in lieu of his patronymic. However, in 1719 he resumed the surname of Grant in lieu of Colquhoun. Grant notably sat as Member of Parliament for Inverness-shire and Elgin Burghs. The seventh and eighth Baronets also sat as Members of Parliament. In 1811 the ninth Baronet succeeded as fifth Earl of Seafield through his grandmother Lady Margaret Ogilvy, daughter of James Ogilvy, 4th Earl of Findlater and 1st Earl of Seafield. The baronetcy remained merged with the earldom until the death of James Ogilvie-Grant, 11th Earl of Seafield, in 1915. The baronetcy then passed to Trevor Grant, 4th Baron Strathspey, and remains merged with the title barony of Strathspey (see Earl of Seafield and Baron Strathspey for further history of the title).

The Colquhoun Baronetcy, of Luss in the County of Dumbarton, was created in the Baronetage of Great Britain on 27 June 1786 for James Colquhoun. He was the fourth son of the sixth Baronet of the 1625 creation. The third and fourth Baronets both represented Dunbartonshire in the House of Commons. The fourth, fifth and seventh Baronets all served as Lord-Lieutenant of Dumbartonshire. As a descendant of the sixth Baronet of the 1625 creation the present holder of the title is also in remainder to this baronetcy. The present Baronet is also Chief of Clan Colquhoun. The family seat is Camstraddan, Luss, Dunbartonshire.

The family surname is pronounced "Cohoon".
