Morgan m. Middle Welsh mawr, Old Breton mor 'great' + Old Breton cant 'perfect, perfection' or Middle Welsh cant throng, host'.

The name of a few early Brythonic and Welsh kings.

Morgan & Morgan s.n. Morgan note two incorrect etymologies of the name which have led to interesting connections between Morgan and other names. They report an example of Seaborn which was "a name intended to translate Morgan", on account of a false etymology deriving the second element from geni 'to be born'. The name has also been connected to Pelagius, due to an identification of the prototheme with Proto-Celtic *mori 'sea'.
