Hi Tricia, I am a Pettit, and my grandfather came from Ballinger Texas. I recently bought a book of the Pettits,Pettets from George Pettet. There is alot of good information about the Pettits. I believe there were Couchs in our line, but right now I have my book out on loan to my brother and would have to look it up to be sure. My grandfather is John McDean Pettit, his father was Cicero Dever Pettit. Sound familiar? Would love to share info.
