Thanks Ron,
I searched the NARA and Broadfoot Records for a Johan, Jean, J Schneider, Snyder, Snider in the 6th TX Field Battery, Willke's Battery and Dege's Battalion. I found a lot of German surnames but nothing close to Johan Schneider.
I did note a John Schneider in the 15th TX Field Battery and the 1st TX Heavy Artillery. Do you "think" this man could be Johan Schneider and did either or both of these units have a connection with Austin or Travis County?
Thanks,
Jim
