If I receive your email address to forward to Kindle, you'll receive from them, my gift, The Irish-American Chronicle, an historical byway lightly traveled, to begin your education. This book contains excerpts from the ancient Druids, Celts & Romans, Irish in the American Revolution (including John Barry & the birth of American's Navy), The Civil War's Valiant Irish (both Blue & Gray), The Last of the Fenians (WW1), The O'Donnells of Philadelphia (WWII), Rory O'Donnell & the Kennedys (covering the 4 days of Hell - 11/22/63 to JFK's funeral) plus much more.
