My great grandfather's obituary (1933)stated that he had served in Captain Baker's Company, Hardeman's Regiment, Hardeman's Cavalry, 3rd Regiment, Arizona Brigade, 31st Cavalry, fought mostly in Arkansas. Everytime I start the looking for information I seem to end up in an endless loop. Granted a pension, 39083, Grayson County. He would probably joined in either Grayson or Fannin County. I have sent for the pension application.
