My name is Valerie. It has been 3 years since your post. I pray you are still on here some. Tyrzah Bates Tubb was John Tubb's mother. They are buried in a small family cemetery in the middle of a cow pasture on Ivy Bluff Rd. in Warren Co., TN. Theirs are the only two graves with headstones. The others are marked with field rocks. John (or Jack) Tubb was my Great Great Grandfather. I saw the name Moses Tubb several times, but could never find the connection. John was a good bit older than Moses (if my memory is correct). Old enough that he could possibly have been Moses' father??? John was on up in years when he married my Great Great Grandmother. Would love to hear from you. Please contact me if you are interested in sharing info.
