Between 1161 and 1175 Reginald,
Earl of Cornwall and a natural son of Henry I, made the gift of a large
tract of moorland to the Prior and Canons of Launceston on the condition
that perpetual payers and masses were said in the priory for his soul and
those of his immediate family. A century later an agreement was reached
between the Prior and the Canons and twelve tenants in respect of grazing
rights, hence the name “Twelve Men’s Moor”. The twelve men agreed to
provide homage and service and an annual rent of four silver shillings
payable at Michaelmas (29th September). The Prior and Canons
agreed that if any of the twelve men should be condemned by verdict of
their peers and the Priors Court of Caradon they
should not be ‘mulched’ of more than sixpence on any one day.
Two men in the deed are Thomas of Calnystocke and David of the same. These are the farms
at West Castick (shown above) and East Castick, both of which are part of the Trebartha Estate. In 1848 both farms bore the name Calstock.
