Solon Johnson Pitts

Hi! I'm looking for information for the Harriman, TN, branch of the Pitts family. My mother is a Pitts by birth, and her father was Marshall Emory Pitts, and his mother was Iva Pearl Pitts and father was Jake Goddard. Iva's father was Solon Johnson Pitts and her mother was Matilda Gordon Pitts Defulvio. I believe Solon's father was Callaway Pitts, and his mother was also Hiley Jane Morgan Acuff. I would like to know if anyone can confirm this and if so, who for certain is Callaway's father. I am under the impression he is the son of a Daniel and Orpha Pitts. I do not know Orpha's maiden name, if she is, in fact, my ancestor. Please, anyone who can help me with this, it would be greatly appreciated. My mother recently discovered a full blooded sister that she thought was only a half-sister(same mother, different father-we thought)and I would like to give this information to my aunt so that she can know her history, too.
