My family tree is full of Odom's and Tucker's. I was raised in Union Parish but have not lived there for several decades. I am descended from the "Four Odom Brothers" (Jesse is my ancestor) who came to Union Parish in ca 1840s from SC thru GA, AL and MS. I have the Odom brothers book compiled by Ouida Nelson and Jay Watters. I am in the process of entering it into a genealogy program so that it can be shared over the web but it looks like it will take several months to get it ready. In my home community, Zion Hill, Odom's and Tucker's were thick. I will exchange information with you.
