Overview
The Rashleigh family is a historic British family whose principal roots lay in Devon and Cornwall. The surname is associated with an estate called Rashleigh in the parish of Wembworthy, Devon, and the family is documented from the fourteenth century or earlier. Over subsequent generations, several branches emerged in Devon and Cornwall, including Rashleigh families based at Rashleigh in Devon, Barnstaple, South Molton, Fowey, Menabilly near Tywardreath, and Coombe in Fowey. The family’s historical importance rests less on a single commercial enterprise than on the accumulation of land, mercantile wealth, political influence, and local prominence. The Fowey and Menabilly branches became particularly significant during the Tudor and early modern periods. Philip Rashleigh, described as a merchant, shipowner, and landowner associated with Barnstaple, acquired the manor of Trenant near Fowey from the Crown in 1545, following the dissolution of the monasteries. He entered trade and built a successful business, although he died in 1551. His sons Robert and John are credited with establishing the fortunes of the Fowey branch. John Rashleigh (1554–1624), a merchant and Member of Parliament, developed the family’s position in Cornwall and began the construction of Menabilly. His son Jonathan Rashleigh (1591–1675), also a merchant and politician, completed the principal development of the family seat. Jonathan sat in the House of Commons at different times between 1614 and 1675 and supported the Royalist cause during the English Civil War. Later generations continued the family’s political and landed presence, including John Rashleigh (1619–1693), who served in Parliament after the Restoration, and Jonathan Rashleigh (1642–1702), who served as Sheriff of Cornwall in 1687. The family also produced figures active in science, industry, military service, and local economic development. Philip Rashleigh (1729–1811) was a Cornish mineral expert and represented Fowey in Parliament. Charles Rashleigh, who died in 1823, was an entrepreneur connected with the expansion of mining in the West Polmear area. He developed a port and settlement on Cornwall’s south coast that became known as Charlestown, a name derived from him. Another member, Harold St. James Rashleigh-Berry, was a British Army lieutenant colonel who served in Peshawar and participated in the Second Anglo-Afghan War under Sir Frederick Roberts. The Menabilly estate remained the family’s most recognizable property. In the 1873 Return of Owners of Land, Jonathan Rashleigh of Menabilly was recorded as Cornwall’s largest landowner, with an estate listed at 30,156 acres. Menabilly’s grounds and country house later acquired a literary association because the estate is widely identified as an inspiration for Manderley, the fictional house in Daphne du Maurier’s novel Rebecca. The family therefore occupies a place in the history of southwestern England through its interconnected roles as landed gentry, merchants, parliamentarians, industrial entrepreneurs, and patrons of a notable estate.

History
The Rashleigh surname is linked to an estate at Wembworthy in Devon and appears in records from the fourteenth century or earlier. The family later divided into several branches across Devon and Cornwall, with notable lines established at Barnstaple, South Molton, Fowey, Menabilly, and Coombe. A major turning point came in 1545, when Philip Rashleigh acquired the manor of Trenant near Fowey from the Crown after the dissolution of the monasteries. He was active as a merchant, shipowner, and landowner, and his commercial success provided the foundation for the family’s later Cornish influence. After his death in 1551, his sons Robert and John continued the family’s advancement. John Rashleigh became a merchant and Member of Parliament and began the creation of Menabilly, the estate that became the principal seat of the family’s Fowey branch. His son Jonathan Rashleigh completed the house and remained active in national politics, sitting in the House of Commons during the seventeenth century and supporting the Royalist cause during the English Civil War. The family’s political role continued after the Restoration. John Rashleigh, the younger Jonathan’s son, served in Parliament between 1661 and 1679. A later Jonathan Rashleigh held the office of Sheriff of Cornwall in 1687. The family’s influence was reinforced by landownership and participation in Cornwall’s economy. Philip Rashleigh, a later member of the family, combined parliamentary service for Fowey with expertise in minerals, reflecting the importance of mining and mineral knowledge in eighteenth-century Cornwall. In the early nineteenth century, Charles Rashleigh became associated with the development of Charlestown on Cornwall’s south coast. The settlement grew as a port serving the mining economy around West Polmear, and its name commemorates Charles Rashleigh. The family also had members engaged in military service, including Harold St. James Rashleigh-Berry, who served in the British Army in Peshawar and took part in the Second Anglo-Afghan War. The scale of the family’s landed position was recorded in the 1873 Return of Owners of Land. Jonathan Rashleigh of Menabilly was listed as Cornwall’s largest landowner, with an estate of 30,156 acres. Menabilly later acquired cultural significance through its association with Daphne du Maurier, who used the estate as an inspiration for Manderley in Rebecca. The Rashleigh family is consequently remembered through genealogy, political history, landownership, merchant activity, mining-related development, and the architectural and literary associations of Menabilly.
