Pencarrow

The Molesworth, later Molesworth-St Aubyn Baronetcy, of Pencarrow near St Mabyn in Cornwall, is a title in the Baronetage of England. It was created on 19 July 1689 for Hender Molesworth, Governor of Jamaica.^[2] The second Baronet sat as Member of Parliament for Lostwithiel and Bossiney. The fourth Baronet represented Newport and Cornwall in the House of Commons. The fifth and sixth Baronets sat as Members of Parliament for Cornwall. The eighth Baronet was a prominent Radical politician and served as Secretary of State for the Colonies from July to October in 1855.

The eleventh Baronet, who had no children, represented Bodmin in Parliament as a Liberal Unionist. When he died, the baronetcy passed to his cousin, who was the son of the Reverend Hender Molesworth-St Aubyn. The twelfth Baronet was great-great-grandson of Sir John St Aubyn, 4th Baronet of the St Aubyn Baronetcy of Clowance, in the County of Cornwall; the Reverend Hender Molesworth had, in 1844, assumed by Royal licence the additional surname of St Aubyn, through his mother Catherine St Aubyn. Thus, Sir St Aubyn Hender Molesworth-St Aubyn, 12th Baronet, brought into being the adjusted name "Molesworth-St Aubyn" for the baronetcy, while also providing a link back to the extinct (since 1839) St Aubyn Baronetcy of Clowance. The fifteenth Baronet was High Sheriff of Cornwall from 1975 to 1976 and also served as a Deputy Lieutenant of the county.
