Some^[which?] martyrologies mention against 16 March a Patrick, bishop of Avernia. Avernia was the Latin name for the Auvergne, but no such Patrick is known there.^{[citation needed]} The reference should have been to Saint Patrick, patron saint of Ireland.^{[original research?]}

The mistake is believed^{[by whom?]} to have been made by a copyist who wrote "Avernia" for "Hivernia" or "Hibernia", and once the second saint got into the martyrologies his feast was moved to another day to avoid confusion.^{[citation needed]}
