De-Anglicisation of Names

MORGAN: Morgan is most often Welsh or Scottish. Either way, it is of Celtic origin and means "sea bright" (?) In Welsh, it was originally Ap Morgan meaning son of Morgan. (Ap corresponds to Gaelic mac.) In Scotland, the progenitor of Clan MacKay (Clann Mhic Aoidh) is Morgan, son of Magnus. The clan MacKay is known as Siol Mhorgain meaning the race of Morgan.

There is some disagreement amongst historians/researchers over who the progenitor of Clann Mhic Aoidh (Clan Mackay) is. There are two train of thoughts:

"The Mackays are descended from the ancient Jarls of upper Sutherland, the northern extremity of Scotland, which makes them originally of Norse blood. But they were in Scotland since very early times, having been derived from those first Norse invaders who settled in the district about the third or fourth century.
Their progenitor was Morgan, the son of Magnus, Jarl of the Orkneys and north coast during the early part of 1300, From him the Clan was called Siol Mhorgain. His son, Donald, married a daughter of MacNial of Gigha, and their son was named Aodh, a Celtic appellation that is difficult for other races to asperate. Several of the ancient Scots Kings bore the name, however, and the early historians translated it "Hugh".

Then we have noted genealogist, Sir Iain Moncreiffe, stating that the progenitor of the Clan Mackay was Eethelred, the son of King Malcolm III Canmore (1058-1093) and descendant from the Pictish Royal House of Alpin, Early Kings of Scots.

Mackay = MacAoidh (Son of Fire) = Mac Eye not Mac Kay
