The Tollemache baronetcy, of Hanby Hall in the County of Lincoln, was created in the Baronetage of Great Britain on 12 January 1793 for William Manners, with a special remainder. He was the eldest son of Louisa Tollemache, 7th Countess of Dysart (suo jure, from 1821), and John Manners (1730–1792), grandson of John Manners, 2nd Duke of Rutland and Member of Parliament for Newark from 1754 to 1774, a rich courtier though of illegitimate birth. On his mother's succession to the title, in 1821, William Manners assumed by Royal licence the surname of Talmash (or Tollemache) and gained the courtesy title of Lord Huntingtower. He was elected to parliament for Ilchester in 1803 and 1806.
Lord Huntingtower predeceased his mother, and was succeeded in the baronetcy by his son, the 2nd Baronet; who later succeeded his grandmother as the 8th Earl of Dysart. The baronetcy and earldom remained united until the death of his grandson, the 9th Earl and 3rd Baronet, in 1935. At that point the baronetcy passed to a male heir, the 4th Baronet, while the earldom passed to Wenefryde Scott, 10th Countess of Dysart.
