Don't let that last post discourage you. Check out the Mason, WV list at genweb or the Scioto, OH listserve. There are tons of cousins working both sides of the river and somebody knows something. Also, check out the publications section of Ancestry.com with your keywords. I know somebody will have information about it. I have gleaned lots of information and I don't live anywhere near the Ohio River. I have met lots of cousins and other helpers. Don't give up.
