What does Eoin mean?
Eoin is an Irish form of John, “God is gracious.”
What does Conall mean?
Popularly glossed as 'strong wolf', from Old Irish 'con' ('hound/wolf') plus a second element. This is DISPUTED: the rigorous etymology derives it from Proto-Celtic *kuno- ('hound') + *walos ('prince, chief'), giving 'strong hound' or 'mighty chief' rather than literally 'wolf'. Flagged as uncertain.
