Grobstein

Devon is derived from the name of the Celtic people who inhabited the southwestern peninsula of Britain at the time of the Roman invasion c. 50AD.
They were known as the Dumnonii, thought to mean 'deep valley dwellers'.
In the Brythonic Celtic languages, Devon is known as Dyfnaint (Welsh), Devnent in Breton and Dewnans (Cornish).

Devon was one of the first areas of England settled following the end of the last ice age.
The area became a frontier between Brythonic Dumnonia and Anglo-Saxon Wessex, and it was absorbed into Wessex by the mid 9th century.
