The Calder clan takes its name from the lands of Calder, located in the county of Inverness-shire, in the Scottish Highlands. The name “Calder” is derived from the Scottish Gaelic word “caldair,” meaning a hard, rocky place or a burn (stream) with rocky banks. The early history of the Calder clan is intertwined with the turbulent times of medieval Scotland. They were considered a part of the ancient Clan Chattan confederation, a powerful alliance of clans in the Scottish Highlands. The clan was said to be descended from the ancient Pictish rulers of the area.
