Is Mc Scottish?

Surnames with the prefix "Mc" and "Mac" are historically Scottish. "O' " is an Irish prefix. It is not uncommon to find any of these prefixes in the British Isles, but especialy in Scotland and Ireland due to their shared heritage."Mc,Mac, stood for "son of" as in MacDonald, son of Donald.Similar to the Scandinavian "son" as in Peterson, son of Peter.In reply to the above Mc or Mac (same meaning) is also historically Irish. Irish Gaelic and Scottish Gaelic are both derived from Old Irish. Mac means son of and O means descendent (grandson of). The Scotti came from Ireland to Scotland around the 5th Century and brought their language and customs with them. Recent genetic studies have backed this up. Both countries have many shared traditions and ancient links. While Mac is used in Scottish surnames the O prefix never was used in Scotland like in Ireland.Not quite true the Scottish surname Hanna had an O prefix originally.
