The manor is listed in the Domesday Book of 1086 as Hiwis, the 2nd of the 28 Devonshire holdings of Gotshelm, one of the Devon Domesday Book tenants-in-chief of King William the Conqueror. He held it in demesne. The tenant before the Norman Conquest of 1066 was an Anglo-Saxon named Alwy. It is today believed to have been centred on the estate of Lovistone, within the parish. Gotshelm was an Anglo-Norman magnate and was the brother of Walter de Claville, also a Devon Domesday Book tenant-in-chief, who as listed in the Domesday Book had 32 holdings in Devon from the king. Before the end of the 13th century the Devonshire estates of both brothers formed part of the feudal barony of Gloucester.
de Hiwis
In Kirkby's Quest, a survey of 1284–1285, the manor of Huish was recorded as being held by Richard de Hiwis, whose family had, as was usual, taken their surname from their seat. According to the Book of Fees, the estate of Lovelleston, within the parish, was however held by Robert Pollard, directly from the feudal barony of Gloucester. According to Sir William Pole the last in the male line of the de Hiwis family was William de Hiwis, who died without issue late in the reign of King Edward III, whose sister and heiress Emma de Hiwis married Sir Robert Tresilian, Chief Justice of the King's Bench, after whose execution she remarried to Sir John Coleshill.
Yeo
relates further that the land was subsequently purchased by Leonard Yeo who built a new house there. The principal seat of the Yeo family had been at nearby Heanton Satchville, Petrockstowe, which had passed by marriage to the Rolles, then by inheritance to the Trefusis family. His descendant, also Leonard Yeo, owned the manor in Risdon's time. The manor remained in the Yeo family until it was sold by Edward Roe Yeo, MP. Various 18th-century mural monuments to the Yeo family survive in the parish church.
Innes-Ker
John Dufty purchased the estate from Edward Roe Yeo who in 1782 sold it to the Scottish nobleman Sir James Norcliffe Innes, later 5th Duke of Roxburghe, who built a new mansion house on the estate, which he called Innes House. He sold the manor to Richard Eales.
Trefusis
In about 1812 Richard Eales sold the manor to Robert Cotton St John Trefusis, 18th Baron Clinton, a member of an ancient Cornish family. Clinton renamed the estate as Heanton Satchville, after his former family home at Heanton Satchville, Petrockstowe, across the valley to the west, which had burned down in 1795. In the early 20th century, following his inheritance from Mark Rolle of the vast former Rolle estates, Baron Clinton utilised the grander Bicton House, the former Rolle seat, as his main residence. However this was vacated in the mid-20th century and the family moved back to Heanton Satchville, which today remains the seat of the Barons Clinton, now the Fane-Trefusis family, the largest landowners in Devon through the Clinton Devon Estates, the lands of which are principally situated near Bicton, in East Devon.
Historic estates
The parish of Huish includes the following historic estates:
Lovistone, which according to the Book of Fees, was held by Robert Pollard, directly from the feudal barony of Gloucester. In the 18th century it was the seat of the Saunders family, most notably John Cunningham Saunders, Esquire, Senior, whose 2nd son was John Cunningham Saunders, Junior, an English surgeon and oculist, best known for his pioneering work on the surgery of cataracts who in 1805 founded the Royal London Ophthalmic Hospital, now known as Moorfields Eye Hospital. Mural monuments to both men survive in the bell-tower of Huish Church. The will of an earlier John Cunningham Saunders "Gentleman of Great Torrington, Devon", near Huish, was proved on 14 April 1744.
