Scota: Mother of Scotland and Daughter of a Pharaoh

During the 1440s, a Scottish chronicler, Walter Bower, sought to trace the history of the Scottish people from the earliest times. The result of his endeavour was the creation of a compendium of Scottish history, the Scotichronicon. Perhaps one of the most astonishing claims made by Bower in his Scotichronicon is that the Scottish people were actually descendants of the ancient Egyptians, and could trace their ancestry to the daughter of an Egyptian pharaoh, Scota.

Now another part of the article and then I'll give you the Source Link.

Scota by Another Name

Not everyone agrees that the Scots originated from Scythia, however. One writer, for instance, speculated that Gaythelos / Gaodhal Glas was neither a Greek king, nor a Scythian, but an Egyptian pharaoh himself. In Scota, Egyptian Queen of the Scots, Ralph Ellis traces the story of Scota and Gaythelos to a 3rd century BC source, Manetho’s Aegyptiaca.

Using this ancient source, it has been argued that Scota was actually Ankhesenamun, the widow of Tutankhamen. Gaythelos, on the other hand, has been argued to be Ay, the successor, and according to Ellis, also the father of Tutankhamen. Due to religious conflict, Ay’s reign was cut short, and the pharaoh and his court were soon forced into exile. Like the Irish legends, Ay and Ankhesenamun wandered around before settling in Spain. Several generations later, there was a migration to Ireland, and thence to Scotland.
