Recently I revisited a family line that I'd left dormant for a while. I offered to try to help my cousin, Barbara Pharo, document members of her family that would qualify for the Hamilton County Century Families lineage recognition. Thomas H. Probert is our common gg-grandfather.
Gathering the required documents led me to try to "prove" that William E. Probert is his father. We have substantial evidence, but nothing that would yet qualify as "proof."
What an adventure! I searched for the Probert surname on the kentuckiana digital library site. This site has many digitized Kentucky newspapers. One of the results puzzled me.
