Search Irish SurnamesSearch our database to find Irish names by county

Many folks who travel to Ireland have some type of ancestral roots, though many don't know exactly where they are from. We're trying to make that a bit easier by allowing you to search our database of over 2,400 Irish names which have been tracked to certain counties in Ireland.

Our database is not comprehensive and there are many variant spellings of names which are not included. In many cases a root name may appear both with and without the O', Mac, or Mc prefix, for example Connor and O'Connor normally indicates the same surname. Although not always the case, names beginning with O', Mac, Mc, De, Le, and others, may usually indicate a name of historical significance. In addition to indigenous Irish surnames (significantly those beginning with O') the list below also contains names of origin outside of Ireland, including Scottish, Welsh, English, Norse, Norman and Flemish, among others origins.
