Few Sullivans appear in Burke's Genealogical and Heraldic History of the Commoners of Great Britain and Ireland. The first, Daniel, is to be found on page 285 of volume 4 under the entry for ORPEN OF GLANEROUGH:
Richard Orpen acquired very considerable property, and from his activit and determined courage, appears to have taken the lead amongst the protestant settlers in that part of Kerry.
