Welcome!
The origins of the Douglas family are lost in the mists of time. It is said that "In the margin, about one-third into The Book of Clan Douglas, Volume III, are written the words: `This is about the time when the Earth began'." (Mary Murray, nee Mary Douglas, of Earltown: 1991).
Perhaps, at the time when surnames were first used, a family took the name of the river that flows though what became known as Douglasdale, possibly descendnats of Flemish settlers.
There is the following tradition in regard to the origin of the name. In the year 770 Solvathius king of Scotland, obtained a victory over Donald Bain of the Western Isles, by the assistance of a man who was unknown to him. After the battle, being desirous to see one who had done him so signal a service, he was pointed out to him with these words: " Sholto Dhuglass," behold that swarthy man.
One of this family, Sir William Douglas, entered into the service of Charlemagne and was the founder of the family of Douglassi in Tuscany.
