In Ronald Reagan & The Isle of Destiny, Matthew Culligan delineates President Reagan's ancestry against the background of Irish history. The author initially furnishes a genealogical overview of the five clans that descend from Brian Boru, the President's ancestor: O'Regan, O'Brien, Hogan, MacMahon, and Murphy. This is followed by a brief narrative history of Ireland, into which are injected accounts of Reagan and related clan members. The focal chapters of the volume, "The Regans in America" and "Ronald Reagan: A Man for Solutions," demonstrate that the President's ancestors numbered individuals who were acquainted with George Washington, served in the colonial Virginia militia, and, in one instance, held the office of Postmaster General of the Confederacy. This charming volume will enlighten anyone interested in the ancestry of one of our most popular presidents.
