A brief history of the origin of the Scots ethnic group and its changes over time.
Gaelic names are pronounced in OLD GAELIC. This is to show the clear link between the English version of names and their Old Gaelic origins. Modern Gaelic has changed in its pronunciation, modern Irish to an even greater degree.
Also note that there is no intent to promote a "pure" Scot, but to demonstrate the core origins and original language. Ethnicity is an evolving thing, as the video shows.
