O'Sullivan (O'Suilleabhainn), the Earliest Irish Royal Family: History and Genealogy. Third Edition (Paperback)

This superb genealogical and historical account traces the O'Sullivan sept a full thirty-one generations from the author's Carolina origins to the family's Irish roots in 170 AD. Mr. McCreight demonstrates that the O'Sullivans may be the oldest documented royal family on record, based on examinations of archaeological, linguistic, and DNA evidence. Little wonder that esteemed genealogist Brian Mitchell calls "O'Sullivan" "a phenomenal piece of research and wide-ranging discussion into the origins of a very significant Irish family and in the process a well-illustrated history of Ireland."
