Att: Cantonjoeocho I do not have y our John O. Sharp in my family line, but I do I have a large number of Sharps. Two brothers, Anthony and Spencer, arrived in Limestone County with their large families in the 1850s. I know that John O. does not belong in Spencer's line, but there are many descendants of Anthony in Limestone and adjacent counties. Then there is Melvin Sharp, whom I believe to be a nephew of Anthony and Spencer. So look to those lines for John O. If you wish, e-mail me and I may be able to help you more. love, joan
