Greg, I saw your two posts. Unless someone else has recently found something new, General Braxton Bragg did not have any children. This from the DAR documents. However, several of his brothers did have children named Braxton.
Just poking around I found what looks like Inas in Screven County in 1910 as a boarder. That makes it hard, since he could have come from anywhere. He's listed in 1920 as well, but you probably know that.
If you go to the http://genforum.genealogy.com/bragg
and search for screven, you'll find a wealth of posts. I didn't see any regarding Inas, but someone there may have some ideas.
On that site you can search for Terry and find my posts regarding Braxton and William, my ancestor. Folks thought I was related to the Braxton Bragg family, but I found evidence to the contrary. Good luck!
