Bagtor is a historic estate in the parish of Ilsington in Devon, England. It was the birthplace of John Ford the playwright and poet. The Elizabethan mansion of the Ford family survives today at Bagtor as the service wing of a later house appended in about 1700.

The feudal barony of Plympton was a large feudal barony in the county of Devon, England, whose caput was Plympton Castle and manor, Plympton. It was one of eight feudal baronies in Devonshire which existed during the medieval era. It included the so-called Honour of Christchurch in Hampshire, which was not however technically a barony. The de Redvers family, first holders of the barony, were also Lords of the Isle of Wight, which lordship was not inherited by the Courtenays, as was the barony of Plympton, as it had been sold to the king by the last in the line Isabel de Redvers, 8th Countess of Devon (1237–1293).
