The Clan/Sept History

Nolan is the English version of the Gaelic Ó Nualláin, which comes from the word "nual" meaning 'famous' or 'noble'. The clan was originally based in Co. Carlow, where in ancient times they were Princes of the Barony of Forth, or Foharta. Some branches of the clan migrated from this area to counties Mayo and Galway and became significant landowners in the area. Today, the name is the fortieth most numerous surname in Ireland, and is strongest in the eastern province of Leinster.
