CRILLY Family History

This is a surname of Irish origins. It derives from the medieval Gaelic Mac Raghallaigh and is said to loosely translate as "The son of the descendant of the rakish one". The majority of Irish clan names originate from a nickname for the first chief, from which it must be assumed that the original chief was a bit of a lad. There are two separate clans or septs which carry the name. Now spelt almost exclusively as Crilly, sometimes Crilley, Crielly, Crelly, or Crolly, and just occasionally found with the O', Mac, or Mc prefix, the nameholders are found either in County Lowth in the Republic of Ireland or as McCroly in County Armagh in Ulster...
