I am writing a book about my ancestors and while I had Polk ancestors in Hardin Co., TN, I also had Lucas ancestors directly across the river in Waterloo, Lauderdale Countyi, AL. I couldn't help wondering if the missing son in the Wm. G. Lucas family could have possibly been the skeleton in the cave, as no trace of him was ever found. The following is from my book: What became of the 12 Lucas children? Those who did not die young, married and/or scattered to the four winds: 1. Thomas, the firstborn, would have been 28 years old at the time of the 1870 census. He was not listed in this census as living in the Lucas home. He may have married and established a home of his own, or he may have been killed in the Civil War. No further information is available about him. A Lucas descendant was told by her mother that one of William Lucas's sons went off on his horse and was never seen again. The horse had been tied to a tree near a river, but had chewed its bridle and returned home. We know what happened to all the other Lucas sons, so it was probably Thomas that disappeared. Ann Rheney
