In addition to the parish an electoral ward exists stretching north of St Ive.[1] The parish used to be a large rural area of rolling landscape with wooded valleys and the population was sparse with the largest village being St Ive itself, located on the A390.The demography of the parish was radically altered with the mid-Victorian mining boom centred on Caradon Hill.[5] Trebeigh, St Ive, in Cornwall was a manor listed in Domesday Book as held by the Earl of Mortain, the largest landholder in that county.[7] Following the Dissolution of the Monasteries the manor of Trebeigh was granted by Queen Elizabeth I in 1573 to Henry Wilbye and George Blyke, from whom it was acquired by John Wrey,[8] who made it his family's chief seat until his descendants inherited Tawstock in Devon from the Bourchiers in 1654.
