you are correct and I do have all that info AFTER 1870's when he married in Allentown and became a father. No clue of his family before but I found a Philadelphia death certificate of Neil McCafferty, in his 40's who was killed in the Union Army in 1864 at Gettysburg but was he my GGFather? Alas, my ancestors had several generations of "Neils, Neals, and a Cornelius so I don't know. First born sons then often were named after the father with only a different middle name as seen in my Irish family of origin.
I need more info to connect the dots between me and the civil war and(hopefully) the Guiness Brewery fortune. (wishful thinking!)
