<spoiler=MacDonald>The surname, MacDonald, means the son or descendant of Donald. Donald is a well-known northern personal name. By some etymologists it is thought to be derived from the Gaelic "donhuil," which means "browneyed." Others say that it comes from two Gaelic words, "domhan"-the world-and "all"-mighty. In Scotch histories of the family the name is always written Macdonald or MacDonald, while those of the clan who have come to America usually use the abbreviation, McDonald.
The clan MacDonald is certainly one of the oldest and most important in Scotland. Its chiefs descended from Somerled, Thane of Argyle, but sometimes styled King of the Isles, who flourished in the twelfth century. [See Chapter (C)].
This clan has been known for centuries for its fearlessness and bravery, and also for its ancient and unbroken lineage. It is well represented today throughout Great Britain and the United States.
The Macdonald clan also styled themselves lords of the isles (meaning the scottish isle) and claimed all taxes and tithes from them
And there you have it
