Two of my g-grandfather's older brothers served in Co. I of the 6th: Wm. B. Temple (bn. Ala. ca. 1838) and John H. Temple (bn. Ala. ca. 1843). Family moved to Henderson Co., Texas (near Brownsboro) in the mid-1850's. John served in the 13th Brigade, Texas Militia prior to war. They enlisted in 6th from Henderson County. Wm. returned from war, John did not.
Hope this helps you somewhat. If you come across any info whatsoever on these two, or can give me reference/research suggestions for the 6th, I would appreciate it. Thanks.
