They descend from Leod, who was the son of Olaf the Black who acquired the Islands of Lewis, Harris and Skye. Olaf died abt 1273.
They are Norse, and not true Scotty Irish.
The two main branches..which came from sons are, Siol Thormoid and Siol Thorcail. And they fought like cats and dogs with each other.
Rory Mor, one of the most celebrated of the Thormoid branch, spent freely on social and economic improvements for those who were in favor to them. They stood by those who stood by them.
