James M. Britnell was 2Lt in Co. E, 4th AL Cav., CSA. This was either William's older brother (my gg grandfather) or his cousin, born 4 years later and with the same name, to Joseph Fletcher Britnell. Another of Wm. brothers, John W., was 2Lt. in Co A, 27th AL Infantry. Listed with enlisted men in Co. E, 4th AL Cav was Benton Britnell, almost certainly Another brother, Charles Benton. I found no record of service for brothers Marvel, Joseph Jasper, or Brantley.
