If your Gilead Ogle is the person who lived near Caldwell in Noble Co. Ohio and died in 1879, then we probably have a common Ogle ancestor. However I cannot find a definite link to our genealogy charts. Your Ogle branch likely follows back to our same Ogle tree but possibly all the way back to when they first settled there around 1800. Do you know the parents of Gilead? Were they of Irish descent?
