Dark-haired or little dark one
Kerion is likely a modern variant of the Irish name Kieran or CiarΓ‘n, derived from the Gaelic word 'ciar' meaning black or dark. It may also be influenced by the Greek word 'kerion', which refers to a honeycomb or a specific type of inflammatory skin condition in a medical context, though the Irish etymology is the primary source for its use as a given name.
