Mostyn-Champneys baronets

The Champneys, later Mostyn-Champneys Baronetcy, of Orchardleigh in the County of Somerset, was a title in the Baronetage of Great Britain.

In 1771 he inherited from his uncle, Anthony Swymmer a sizeable plantation: Nutt's River, in the parish of St Thomas in the East, Surrey, close to Morant Bay, Jamaica.

[1] Leaving his wife and children in England, Champneys spent several years (1784–90) in Jamaica, joining the local Trelawney Militia as an artillery superintendent [1] and overseeing the Windward coastal fort [2], in addition to being a magistrate in the parish of St Thomas in the East and St David Surrey.

His financial affairs deteriorated; his father-in-law, Richard Cox, stepped in and by the turn of the 19th century had mortgaged all Champneys' properties, his remaining manors of Orchardleigh and Frome Selwood, along with Nutt's River, foreclosing on the eventual bankruptcy.

In 1821 Sir Thomas assumed by Royal Sign Manual the additional surname of Mostyn.
