Nick,
David Haimerl did an intensive analysis of the CSR's for members of Well's Texas regiment [formed from the various battalions and squadrons that you've mentioned.]
He posted his research in a 25 part series on this board in 2006.
Here is a link to part V of this series

The other parts can be found via the search function on this message board.
Hope this helps.
