The original code and data for the Placenames, Surname search, Subscription and Ancestor search sections of Irish Ancestors come from GRENHAM'S Irish Recordfinder, a stand-alone expert system for Irish genealogy. You can find out more at John Grenham's web-site.
The Browse section of Irish Ancestors is based on the fourth edition of John Grenham's Tracing your Irish Ancestors. This was published in 2012, by Gill and Macmillan outside the U.S. and in the U.S. by the Genealogical Publishing Company, and is available online from both firms.
