“Fergus (subking of a Tuatha called Dalriada) colonized a part of Scotland in 470 AD that was nearest his Tuatha in Ulster, i.e. the present Argyll and gave his new Kingdom the name Dalriada. From this little colony the Irish colonists gradually spread over Scotland until the whole of Scotland was governed by the kings of the Dalriada line. That is why the native language of Scotland is Gaelic and akin to the Irish very closely.” Casserley, D., History of Ireland, Talbot Press Limited, Dublin and Cork as summarized by Beryl F.E.
