Your Patrick is my great great uncle. He was brother of michael and John jr., sons of John sr. John jr and sr came to Williamsport via Baltimore in 1851. Patrick and Michael came via Philly in 1852. All were naturalized together. I have a copy of their original application and John jr.s u.s. citizenship certificate. John jr.
