Francis Rashleigh Rodd was born on 10 March 1839 at Trebartha Hall, the son of Francis and Mary (née Rashleigh) Rodd. The family held the Trebartha estate near North Hill on the eastern side of Bodmin Moor. He was educated at Eton and at Christ Church, Oxford, where he took a second class in honours. In 1880 he succeeded his father as head of the Trebartha estate.
On 7 February 1882 he married Julia Eleanor Dorothea Graves Sawle at Heavitree, Exeter. The marriage produced no children. In his twenties he suffered an accident that left him almost blind, an impairment that affected the rest of his life. He became a strong supporter of the Institute for the Blind and maintained an active interest in charitable work connected with visual disability. Despite his sight loss he continued to play a prominent role in local affairs.
Rodd entered public life at an early age. He was appointed a magistrate for Cornwall while still a young man and for many years sat on the Launceston County Bench. He also served on the Launceston Board of Guardians and the Rural District Council. He was a generous supporter of the Launceston Infirmary and Rowe Dispensary and acted as one of its trustees. Only in later life, when his health declined, did he withdraw from most of his public duties.
An Anglican by conviction, he was patron of the Bolventor benefice. His father had built Bolventor Church, and Francis, then eight years old, laid the foundation stone. Politically he was a staunch supporter of the Unionist (Conservative) party, but contemporary accounts emphasise his tolerance of those whose views differed from his own and his reluctance to engage in personal or partisan attacks.
The Trebartha estate extended beyond North Hill, with land reaching westwards towards St Erth and Hayle and substantial acreage around Bolventor. As a large landowner he was regarded as conscientious and fair. He took a personal interest in the welfare of his tenants and was remembered locally as a considerate landlord. An elderly tenant at his funeral described him as “a good landlord—none better—a kind‑hearted gentleman”, a judgement consistent with other reports of his management of the estate.
Rodd’s intellectual and scientific interests were wide. He had a strong appreciation of the classics and was a Latin scholar. He was recognised locally as an authority on natural history, geology, forestry and archaeology, drawing heavily on the varied landscape of the Trebartha estate and the surrounding moor. His botanical interests led him to support the Launceston Cottage Garden Society, where he was both a member and an exhibitor, and he also exhibited at shows in London and Plymouth. His observations on plants, trees and land use were valued by local antiquarian and natural history circles.
In later years his health deteriorated and he spent increasing periods confined to his room at Trebartha Hall. He died in June 1922 at the age of eighty‑three after a long illness, having been largely confined for the last six months of his life. The cause of death was recorded as senile decay. His funeral took place on 14 June 1922 at St Torney’s Church, North Hill, conducted by the Reverend T. R. Willing. The church was filled, with just enough room for the procession, reflecting his long association with the parish and his position in the local community.
