Names, Names, Names, all the same names. How can I keep it all straight? Who belongs 2 who?
First, this is every genealogist nightmare but a great question. Keep a separate chronology for each person's life including any information that distinguishes them from a cousin, etc. Maybe a description of their land or tax detail. If the wife's have the same name, certainly the children's name are different. They might go by a nickname such as junior or senior. However, remember that doesn't mean they are father/son. It could be two people with the same name in the same town. To keep it all straight in your head, try using their middle initial or their nickname.
