Patti,
I beleive the 1864 is a typo, from regimental records at footnote the 35th was in south Texas. Camp Wharton in Mar 1864, then to the Houston, Galveston area from May until Sept 1864 when they went to Camp Ford until sometime after the first of the year, when they went to Boonville which was 2 miles from present Bryan,Tx.
