I don't know if he was your John Henry Pool or not.
I'd contact the Oregon County Genealogical Society, www.rootsweb.ancestry.com/~mooregon/ocgs.htm
and ask if they'll look up his obituary.
If he owned property the Oregon County Circuit Court will have his will/probate info too. Successful Searching!
