Glasco History, Family Crest & Coats of Arms
In ancient Scotland, the first people to use Glasco as a surname were the Strathclyde-Britons. It was a name someone who lived in the city of Glasgow on the river Clyde in the county of Renfrew (first recorded in 1116 as Glasgu), or from either of two minor places with the same name in Aberdeenshire. The origins of the place name are uncertain, it may come from the Welsh glas, or "gray," and cau, meaning "hollows."

The persecution faced in their homeland left many Scots with little to do but sail for the colonies of North America. There they found land, freedom, opportunity, and nations in the making.
