Houston baronets
There have been two baronetcies created for persons with the surname Houston, one in the Baronetage of Nova Scotia and one in the Baronetage of the United Kingdom, both extinct. The Houston Baronetcy, of Houston in the County of Renfrew, was created in the Baronetage of Nova Scotia on 29 February 1668 for Patrick Houston. The third Baronet represented Linlithgowshire in Parliament. After the death of the eighth Baronet in circa 1835, no-one successfully claimed the title, although there were living heirs. The Houston Baronetcy, of West Toxteth in the City of Liverpool, was created in the Baronetage of the United Kingdom on 17 January 1922 for the shipowner and Conservative politician Robert Houston. The title became extinct on his death in 1926. His wife Lucy, Lady Houston, was a benefactor and philanthropist. Houston baronets, of Houston (1668)
