I take it that you have different idea of commoners than most. Diana was some sort relative introduced to Charlie boy by his granny and for someone brought in a council house would appear to be far from common as is the current royal future bride.

You should reread your history. The present royal family have no historic connections to any British/Scotish line - remember importing William of Orange? I think he was Dutch.

Still "The man of indepent mind, He looks and laughs at a' that".

Did the lord of the ilses attend the opening of Scottish Parliament, I thought it was his mum.
