Gray valley or gravelly valley
Graeden is a modern English surname-style name likely derived from the Old English elements 'graeg', meaning gray, and 'denu', meaning valley. It may also be a variant of the name Gradon, which refers to a gravelly hill or settlement. As a contemporary invention, it follows the popular trend of two-syllable names ending in the 'den' sound.
