- Trollope Baronets
The Trollope Baronetcy, of Casewick in the County of Lincoln, is a title in the Baronetage of England. It was created on 5 February 1642 for Thomas Trollope. The seventh Baronet was a Conservative politician. In 1868 he was raised to the Peerage of the United Kingdom as Baron Kesteven, of Casewick in the County of Lincoln. The barony became extinct in 1915 when the third Baron was killed in action in the First World War. The late Baron was succeeded in the baronetcy by his cousin, the tenth Baronet.
The author Anthony Trollope was another member of this family.
