The pronunciation of "dahn" was introduced by the McCockerknees from the lowlands (lowlands low) (they had to be born within the sounds of Gorbells)so as to differentiate between "doon" which also means a small expanse of sand. Not wanting to do with anything "expansive" (you know the Scots and their wallets!) they preferred "dahn", OK?
