* This company subsequentiy became company E 30th Regiment Texas Cavalry AKA as Gurley's Regt Texas Cavalry and 1st Regt. Texas Partisan Rangers, it was organized August 18,1862 with 10 companies A thru K. ( The letter J was not used. )
Note: there was at least 2 Camp McCulloch in Texas, 1 near Tyler and 1 near Waco knowing that Buchanan is in Johnson county I would bet on the 1 at Waco be 65 miles away.
