The import of this Celtic name is At-Minos, i.e. the devotee to, or the votary of, Minos.  The father of Cunobeline, according to the ancient British Chronicles, is invariably represented as a most rigid observer and administrator of justice.  The Chronicles appear to be worthy of credit in relating this; and it may be regarded to have been to please his father in his ideas, that he named one of his sons Adminius, or "a votary of Minos," a person who had been in his day one of the most celebrated lawgivers of antiquity...
    The name of Adminius on coins is Amminus, and at other times Aedd, which we know is by no means an unusual Celtic name, and according to Richards (see his Dictionary) is the same as the Latin appellation Aëtius. (Celtic Inscriptions on Gaulish & British Coins, Poste, 1861)
