Show ContentsGlasco 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."

They fought for their freedom in the American War of Independence, or traveled north to Canada as United Empire Loyalists. In both cases, they made enormous contributions to the formation of those great nations. Among them:
