PATRICK and ELLEN were the parents of JOHN, PATRICK, MARTIN , JOSEPH and others who came to the U.S. in the 1850's and settled in and around Baltimore MD, (ELLICOTT CITY). John was born abt 1826 in MAYO and married Ann Martin in MD. Any Irish cousins out there who can help me learn more about Patrick and Ellen? So far I have no evidence they came to America. HELP!!!!
