Williamson baronets

There have been two baronetcies created for persons with the surname Williamson, one in the Baronetage of England and one in the Baronetage of the United Kingdom.

The Williamson Baronetcy, of East Markham in the County of Nottingham, was created in the Baronetage of England on 3 June 1642 for Thomas Williamson. He was a supporter of the Royalist cause in the Civil War, which loyalty resulted in the sequestration of all his Nottinghamshire estates, for which he compounded at a cost of £3400.

The family removed to County Durham as a consequence of marriage and from the 18th century the family seat was Whitburn Hall, near Sunderland ( the house was demolished in 1980). The fourth Baronet served as High Sheriff of Durham 1723–1747. The fifth (1747–88) and sixth Baronets (1789–1810) also served in that office. The seventh Baronet sat as Whig Member of Parliament (MP) for County Durham 1831–2, and Sunderland 1847 and was High Sheriff in 1840. The eighth Baronet represented Durham North in the House of Commons 1864–74. The ninth Baronet was High Sheriff in 1904. The title became extinct on the death of the eleventh Baronet in 2000.

The Williamson Baronetcy, of Glenogil in the County of Forfar, was created in the Baronetage of the United Kingdom on 29 July 1909. For more information on this creation, see the Baron Forres.
