The term "Devon" is normally used for everyday purposes e.g. "Devon County Council" but "Devonshire" continues to be used in the names of the "Devonshire and Dorset Regiment" (until 2007) and "The Devonshire Association". One erroneous theory is that the "shire" suffix is due to a mistake in the making of the original letters patent for the Duke of Devonshire, resident in Derbyshire. However, there are references to "Defenascire" in Anglo-Saxon texts from before 1000 AD (this would mean "Shire of the Devonians"),[2] which translates to modern English as "Devonshire". The term Devonshire may have originated around the 8th century, when it changed from Dumnonia (Latin) to Defenascir.[3]
