Orcadians, also known as Orkneymen, are an ethnic group native to the Orkney Islands, who speak an Orcadian dialect of the Scots language, a West Germanic language, and share a common history, culture and ancestry. Speaking Norn, a native North Germanic language into the 19th or 20th century, Orcadians descend significantly from North Germanic peoples, with around a third of their ancestry derived from Scandinavia, including a majority of their patrilineal line. According to anthropological study, the Orcadian ethnic composition is similar to that of Icelandic people; a comparable islander ethnicity of North Germanic extraction.
