About old Irish baby names

The Ancient Irish, like the Greeks and Hebrews, were called by only one name — such as Aonghus, Diarmaid or Domhnall.

However, for the sake of distinction, a name derived from some personal peculiarity — or a patronymic formed by prefixing “Mac” to the genitive case of the father’s name, or “O” to that of the grandfather — was sometimes added.

ALSO SEE: What does Mc/Mac mean in a last name?

Last names, in the modern sense, were unknown in Ireland before the tenth century. This usage necessitated a large number of names, and led to the formation of a very varied and interesting Gaelic personal nomenclature.

Some of these names, no doubt, lived only for a short time and have long since entirely disappeared; but we have names — like Art, Aodh (which would be the modern-day Aidan), Cian (Sean), Comhghan (Cowan), Diarmaid (Dermot), Domhnall (Donald), Eoghan (Ewan/Owen), etc. — that have been in uninterrupted use from the earliest period of which we have any record down to the present day.

Many others, though long obsolete as first names, are still preserved in our surnames.
