Johnston baronets

There have been four Baronetcies created for persons with the surname Johnston (as distinct from Johnstone), two in the Baronetage of Nova Scotia, one in the Baronetage of Ireland and one in the Baronetage of the United Kingdom. One creation is extant as of 2010.

The Johnston Baronetcy, of Caskiebien in the County of Aberdeen, was created in the Baronetage of Nova Scotia on 31 March 1626 for George Johnston.

The Johnston Baronetcy, of Elphinstone in the County of Haddington, was created in the Baronetage of Nova Scotia on 18 October 1628 for Samuel Johnston. Nothing further is known of the title after the death of the third Baronet in circa 1700.

The Johnston Baronetcy, of Gilford in the County of Down, was created in the Baronetage of Ireland on 27 July 1772 for Richard Johnston, later a member of the Irish House of Commons for Kilbeggan and Blessington. The title became extinct on the death of his son, the second Baronet, in 1841.

The Johnston Baronetcy, of London, was created in the Baronetage of the United Kingdom on 22 January 1916 for Charles Johnston, Lord Mayor of London between 1914 and 1915. The title became extinct on his death in 1933.
