Greenes and Seals and Ogans in Hancock County, TN

I am working on a family tree. My family mainly came from Hancock County,TN. My grandparents are Charles Henry Greene and Viola Elizabeth Seals Greene. My Great grandparents are Tyler Greene and Ruth Ogan Greene. Have heard of a book that was wrote by Alton Greene. Would love to find one to buy or even look at the book.
