Toponymy
The Scottish Gaelic name "Taobh a Deas Chas Chaolais" means " Southern Side of Steep Strait". The name "Cas Chaolas" (Steep Strait) is older than the English name; it can be applied to either North or South Queensferry, or both. The queen referred to is Saint Margaret of Scotland who is believed to have established a ferry at this point for pilgrims on their way north to St Andrews. She died in 1093 and made her final journey by ferry to Dunfermline Abbey. Her son, David I of Scotland, awarded the ferry rights to the abbey.
