The names Ireland and Éire both derive from Old Irish Ériu, which in turn comes from Proto-Celtic ɸīweriyū meaning “fertile soil”. The Classical Latin name for the island of Ireland, Ivernia, also comes from this same root
Not sure why you’re mentioning Ireland, did you think it was named after Kathy Ireland?



























Ériu, Banba and Fódla are from Lebor Gabála Érenn, Ireland’s creation myth, and they each wanted the whole country named after them (and still can be, poetically). This is a mythologised history, not etymology.
Also, downvoting someone you’re debating with is extremely bad form.
