I don't think I can answer your question directly, but I am also from the Estep/Sweeney line. I can't go back to the 1880s or so from the West Virginia/kentucky line, but that is about where I stopped finding things. So you have, by any chance, a history of young deaths....drowings, seizures, heart conditions? We just got a diagnosis on my son for Long QT syndrome that causes sudden cardiac arrest in the young, as well as faining spells that are usually misdagnosed as seizures. Any of that ring a bell in your research?
