My John Sisco was born 1806 Roan County, TN. and Elizabeth born January 16th, 1807 in TN. There are a few John's in this families downline but they are not married to an Elizabeth, these may be indeed your people but; I'm not sure I've seen so many Sisco's it's nerve wracking aint it? Maybe either the Brawner/Bronner family book or the Shrum/Schramm family book BOTH recently completed geneaology works would be a good investment for you I know these two books are on my list for Christmas! I'm NOT a "paid up member of this site" so any correspondence is best sent to me at block@thurston.com and I delete all spam so include something REALLY revelant to me in title of email or I'll delete! It's suirvival instinct sorry! Neal Shrum
