The Houstoun, later Houstoun-Boswall Baronetcy, is a title in the Baronetage of the United Kingdom.
The title was created on 19 July 1836 for General Sir William Houstoun, GCB.[1] The second Baronet was a Colonel in the Grenadier Guards. In 1847 he assumed by Royal licence the additional surname of Boswall on his marriage to Euphemia, daughter of Thomas Boswall.[2] The sixth Baronet, whose father Colonel Thomas Alford Houston-Boswall-Preston had assumed by Royal licence the additional surname of Preston in 1886,[3] discontinued the use of the surname Preston in 1953.
The seat of the baronetcy was the country manor of Calderhaugh, or Calderhall (Calder Hall), Kirknewton, West Lothian, Scotland until 1800, when the residence was sold to Dr. James Hare and the Hare family, and demolished. The Hares rebuilt a new Calder Hall in the Greek Revival style, designed in 1824 by the King's architect Robert Reid (c. 1774–1856), which stood for over a century before falling to ruin. It was demolished in 1970 to build more housing to accommodate the population growth of East Calder.[4][5][6]
