My Peter DUNCAN was born abt 1820 in Dublin Ireland. He and his wife, Mary Catherine MCMURRAY came to US around 1841 and their 1st son John was born in New York abt 1842. They then went to Carbondale, Pa. where he was a miner. Daughters Margaret and Mary were born there. The faamily then moved to Sheffield, Bureau Cty. Il. where Bridget, Alice, Thomas and Peter were born. The father and later the boys all worked in the Coal mines there. Margaret married James ODEA in Sheffield and their children were Mary (Minne), Peter,John, Matthew, Vincent and Katherine. The ODEA family eventually moved to Davenport, Iowa. Any connections? Any info about this famil would be appreciated.
