Based on the numbering schema (which was very poorly done) I would have to say Isaac number 2 was the son of the original Isaac. It should be number as A (Isaac #1) then 1-? for his children (Francis, Joseph, etc). Boy some people and their crazy numbering schemas. Remember there is always somebody out there that has an even dumber question that the one you come up with. Always try to create info that is understandable by people who dont know you. Remember other people cant read your mind!!! Richard
