My sources: some from a family Bible, most from a copy of Z's will. If you give your address, Ill send you a copy of the will and the Bible pages. My sister has the Bible but she send me a copy of the pertinent pages. The Bible has the information about James Berenton, the baby of Z and Mary. Also, I've seen it somewhere in one of the Indiana books about the olden days. Those books are on line and you just have to rummage through them.
Also, I'm pretty sure that Mary and James Berenton are buried in Alpha. Look again.
I found some information about some of Z's other children through census information. I have that summarized if you're interested. I still can't find Z's and E's antecedents. Do you know?
