I'm seeking the impossible! My immigrant ancestor, JOSEPH MC MAHON, born 1828, was "from Monaghan" and that's all I know. We do not have a father's name nor the name of any other family member. He arrived in Philadelphia in 1847, became a tailor, married SARAH ANN LEWIS, a seamstress, and had six children: Mary, Sylvester, John, Joseph, James Paul, and Maurice. Almost all the family has remained in Philadelphia, and a few of us are in California. We descendants of Joseph, James Paul, and Maurice are doing well with our U.S. research but would welcome connections with descendants of Mary and Sylvester. John died unmarried. Thanks! Ann
