Hi! I am researching the names of McMahon and McNerney for my wonderful Mother-in-Law in Mercer County, Pa. Her 2nd gr. grandparents were Patrick McMahon, b. 1835 in County Clare, Ireland and Bridget McNerney, b. 1835 also b. in County Clare. Children, Ellen, Mary, John, Mike, Bridget and Katherine. Any information would be appreciated. Pam gennut@nauticom.net
