Debra,
Hi, I had a grandfather (Charles Williamson) and an uncle (Soloman Fletcher) in company B, 6th Texas Cavalry.
Here is a link with some info. a good list of books on Ross and the 6th. Mr. Keen's book, Living and fighting with the 6th Texas Cavalry is a great little book.

I hope this helps you in some way,
