“Possibly hard, rushing water”

A Scottish surname taken from a river name. Most scholars trace it to Brythonic (Celtic) words related to the Welsh caled, meaning 'hard', and dwr, meaning 'water', possibly describing a rocky riverbed or a fast, forceful current. Now also used as a modern given name, mainly for boys.
