Regina, Thank You for your help. It's clearer now. I want to ask you for one last favor. On the 1870 Census, Robert is 75, Nero is 41, and Peter is 25. What's your best guesstimate, is Robert the father of both Nero and Peter, or the father of Nero only, and the grandfather of Peter? In other words, is it more likely that Nero and Peter are brothers, or father and son?
