The ten most popular Irish last names

What was the ranking for Clancy/Clancey?

OK

This is all relative to the time frame the names are chosen as popular. But well written and interesting.

debbieJR - Duncan is an ancient Celtic name, primarily of Scottish Clan origin. Originally a forename, meaning 'brown battler' - from Celtic words 'Donn' (brown) and 'cath' (battle) - it later became a surname for the descendants of the original ancient Duncan kings of Scotland. It exists in Ireland to a lesser extent, mostly in Nth Ireland, than as exists widely in Scotland today, funnily enough back in use as a forename. The Irish forename, Donnacha, is used often in Ireland as a translation of Denis or Dennis, originally a French or German name, I think. Celts lived over wide parts of Gaul (in France) and German hinterlands, so Dennis is a popular name in Germany and parts of France still today.

I'm happy with the ones of my ancestors.

Number 10 - Yeah Baby, all hail the Cavan Reilleys!

Most popular? Are we not born into a surname? "Popular" indicates a preference. First names may or may not be popular but surnames are handed to us at birth. Perhaps you meant to say The ten most COMMON Irish last names. Then there are the most SPECIAL Irish surnames, one of which is DOOLEY.
