The portion on the west side was transferred to Cornwall by the abolition of Broadwoodwidger Rural District by the Local Government Commission for England in 1966.
White's Devonshire Directory (1850) described the parish of Werrington as being near the River Tamar and the Bude Canal and having an area of c. 5,000 acres.
[13] The "steward of the court of the Earl of Bedford" at Werrington in about 1600 was John Twiggs, whose family pedigree is included in the 1620 Heraldic Visitation of Devon.
[13] The estate was sold in 1651[17] to Sir William Morice (1602–1676), Secretary of State to King Charles II,[2] who also purchased from the Drake family the manor of Launceston.
The present mansion, today known as Werrington Park was built by one of his descendants in the 1730s, possibly to the design of William Kent,[18] which involved the demolition and re-siting of the parish church of St Martin.
The estate was acquired in 1882 by John Charles Williams (1861–1939) of Caerhays Castle,[13] who renovated the house, including a re-modelling of the East Range.
A settlement of the dispute was made in 1500 in favour of the priory which undertook the cost of a resident chaplain to serve both Werrington and St Giles.
