In 1814, long before the Bolitho family acquired the estate, Rose Price (1768-1834) purchased Trengwainton. Price was part of the Cornish establishment, a magistrate, and in the coming years was knighted (1815) and appointed inaugural president of the Penzance Library (1818). His wealth came from inherited sugar plantations in Jamaica and spent at Trengwainton, where he created a landed estate with gardens in the picturesque style.

Please be aware

The following web page discusses the legacy of colonialism at Trengwainton and historic slavery and includes references to histories that some people may find upsetting.

The Price family and Jamaica

The Price family owned large sugar plantations on Jamaica. They descended from Francis Price (1635-1689) who was believed to be a junior officer at the island’s conquest of 1655. Francis acquired his first Jamaican plantation in 1663, and subsequently bought further estates. In 1670, after England gained formal possession of Jamaica, he acquired 840 acres which he named Worthy Park.

Worthy Park passed through the hands of various members of the Price family, including John Price of Penzance the Younger (1838-97), Rose Price’s father. John Price was mostly absent from Worthy Park, running his plantations from England through local agents. His son Rose Price was educated at Penzance Grammar School, Harrow and then Oxford University, before embarking on a Grand Tour.

In 1791 the family estates in Jamaica, including Worthy Park, were in trouble owing to unscrupulous local agents. Rose Price travelled to Jamaica to assume direct management, where it is claimed he doubled their value.

The enslaved people at Worthy Park

Rose Price made detailed records which survive in his great plantation book, covering the years 1792-96, now held by the Library of Congress. In this we learn he expanded sugar-cane cultivation by 25% within three years. In order to achieve this, Price had expanded the number of enslaved people at Worthy Park from 355 to over 500. He also introduced adapted Cornish mining technology for mills and brought Cornishmen to assist in the plantation management.

The enslaved people working at Worthy Park came predominately from Africa. They, and their descendants, were deployed in the harvesting of sugar cane, but also worked in the production of sugar and rum. Others worked as carpenters and blacksmiths, a midwife and nurses, and in the 'great house' worked a 50-year-old cook named 'Penzance'. In his great plantation book, Price records the birth of two children with Lizette, a 13-year-old enslaved child, during the three years he spent at Worthy Park. Once older, he sent them to England to be educated.

Rose Price and Trengwainton

Rose Price returned from Jamaica in 1795 and that year married Elizabeth Lambert, niece of Lord Sherborne in Gloucestershire. His income from Jamaican estates was then around £6,000 a year, and he continued to invest in further plantations.

Price remained committed to slavery and became a staunch anti-abolitionist. In 1832, whilst living at Trengwainton, he wrote a defence entitled Pledges on Colonial Slavery, to Candidates for Seats in Parliament, Rightly Considered. This included his response to a pro-abolition article published in the West Briton on 7 December 1832. In his response, Price claimed, by giving various examples, that the treatment of enslaved people on plantations in Jamaica was better than of most labourers in England, and 'milder' than in ancient Egypt, Greece and Rome. His defence of colonial slavery is followed by printed letters in support of his view.

Rose Price died soon after British Parliament passed the Abolition Act in 1833. His executors later received over £10,000 compensation awarded to owners of formerly enslaved people. Despite this large sum, Price’s finances were not sound: he had encumbered both his Jamaican and Cornish estates with substantial debts, and Trengwainton was sold by its mortgage holders in 1835.

We know that there is still work to do in interpreting and exploring this part of history attached to Trengwainton garden and are working with partners through the Inclusive Global History project. Please contact Claire North ( for further information.
