Recorded highest by Republic of Ireland
Names whose best recorded position across all seven registrars comes from Republic of Ireland. Where two registrars gave a name the same best position, it appears under one of them only.
Where a name ranked highest in the data Namewise holds — never where it is most used. The seven registrars publish lists of different depths, over different periods, for populations of very different sizes, so a name can rank higher in a smaller country's list without more children being given it anywhere. Ties are broken consistently, so each name appears under exactly one registrar.
