High Quality Content by WIKIPEDIA articles! The Cornish (Cornish: Kernowyon) are a people associated with Cornwall, a county and Duchy in the south-west of the United Kingdom that is seen in some respects as distinct from England, having more in common with the other Celtic parts of the United Kingdom such as Wales, as well as with other Celtic nations in Europe. For some, the Cornish represent a distinct ethnic group within the UK, which can trace its roots to the ancient Britons who inhabited southern and central Great Britain prior to the Roman conquest, and some in the county today continue to assert a distinct identity, separately or in addition to English or British identities. Cornish identity has been adopted by migrants into Cornwall, as well as by emigrant and descendant communities from Cornwall, the latter sometimes referred to as the Cornish diaspora.
