The Dartington Hall Trust is based on an historic estate near Dartington in south Devon. The estate was held by the Martin family between the early 12th and mid 14th centuries but on the death of William Martin in 1326, the feudal barony of Dartington escheated to the crown and in 1384 was granted by King Richard II to his half brother John Holland, 1st Duke of Exeter (c.1352-1400), created in 1388 Earl of Huntingdon and in 1397 Duke of Exeter.
