The information I have says that William and his wife, Mary (maiden name is possibly Kennedy), were both born in Ireland around 1815-1820 (based on census data) and settled in Herrick Township, Pennsylvania around 1840 (according to a history of the town). Children include Thomas, John, and Isaiah. Basically, I've been trying to find out more about their time in Ireland and their family histories in the area. If anyone has any leads, that'd be much appreciated!
