The village is mentioned in the Domesday Book as "Dune" with the manor belonging to Count Alan of Brittany. The lordship of the manor was granted by the Count to Gospatric, son of Arnketil around the time of the Norman Conquest. There were two ploughlands with a taxable value of 3 geld units.[2] The manor came into the possession of Thomas de Richeburg before passing to the Leyburn family around 1184. Over the following years they granted the manor piecemeal to the abbey of St Agatha at Easby. The abbey then granted the manor lands to the Cleasby family by the middle of the 13th century. Around 1314, the Cleasby's passed the manor on to the Scrope family of Castle Bolton.[3][4]
The etymology of the name is derived from the Old English word dūn meaning hill. As can be seen from the Domesday Book entry, the suffix of -holme, Old English holegn for holly, was added a later date.[5][6]
Geography and governance
The village lies on the A6108 road between Leyburn and Richmond on a section called Walburn Head. The nearest settlements of Marske, Hudswell, Stainton and Marrick all lie within 2.5 miles (4 km) of the village. Church Gill, which has a small waterfall, runs north through the village to join the nearby River Swale, whilst other small waterways to the east of the village drain away to Risedale Beck. The village gives its name to the Moor between it and nearby Hudswell Moor. The high point is Seat How at 312 metres (1,024 ft) to the south-east of the village. There are visible signs of old quarries and coal and lead mining shafts on the hillsides surrounding the village. There is also evidence of a Bronze Ageunivallate hill fort on How Hill to the immediate west of the village.[7] The geology of the area is made of Yoredale rock, Limestone, Shale and Millstone Grit covered by Clay.[3][8]
The village lies within the Richmond (Yorks) UK Parliament constituency. It also lies within the Upper Dales electoral division of the North Yorkshire County Council and the Swaledale ward of Richmondshire District Council.[8]
In 2012, the neighbouring Hudswell Parish Council put forward a proposal to merge the two parishes.[9]
