There have been two baronetcies created for people with the surname Heathcote, both in the Baronetage of Great Britain and both created in 1733. The holders of the first creation were later elevated to the peerage as Baron Aveland and Earl of Ancaster, which titles are now extinct. However, both baronetcies are extant as of 2008[update].
The Heathcote Baronetcy, of London, was created in the Baronetage of Great Britain on 17 January 1733 for Gilbert Heathcote, Lord Mayor of London in 1711 and one of the founders of the Bank of England. His son, the second Baronet, represented Grantham and Bodmin in the House of Commons. He was succeeded by his son, the third Baronet, who sat as a Member of Parliament for Shaftesbury. His son, the fourth Baronet, represented Lincolnshire and Rutland in Parliament as a Whig. On his death the titles passed to his son, the fifth Baronet. He sat as a Member of Parliament for Boston, South Lincolnshire and Rutland and served as Lord Lieutenant of Lincolnshire. In 1856 he was created Baron Aveland, of Aveland in the County of Lincoln, in the Peerage of the United Kingdom. Lord Aveland married Clementina Drummond-Willoughby, 24th Baroness Willoughby de Eresby (a descendant of the Dukes of Ancaster and Kesteven). They were both succeeded by their son, the second and twenty-fifth Baron respectively. In 1872 he assumed by Royal licence the additional surnames of Willoughby and Drummond. Lord Aveland represented Boston and Rutland in the House of Commons as a Liberal. In 1892 the Ancaster title held by his maternal ancestors was revived when he was made Earl of Ancaster, in the County of Lincoln. He was succeeded by his son, the second Earl. He sat as a Member of Parliament for Horncastle and served as Lord Lieutenant of Rutland.
