Edling

Edling was a title given to the agreed successor or heir apparent of a reigning Welsh monarch. The title comes from the Old English word Æþeling "noble child", which was used in Anglo-Saxon England before the Norman Conquest to denote one of "royal blood".The corruption in Welsh use had a more precise meaning and denoted the acknowledged heir to the throne, usually the ruler's eldest son, even though any son, legitimate or illegitimate, could be chosen as edling.
