Rick, The only Hanson I see that was in the 1st Texas Inf Co L and the 12th Texas Cavalry (Parson's) was a John Hanson. He went in the 1st Texas Inf as a Pvt and came out a Sergeant. He was a Pvt in the 12th Texas Cavalry. If this is your man you can order his military records by cllcking on the Red Box above.
