I'm convinced the SOS cards from Capt F. W. Little "District of the Border Military Militia" (Which is a new one to me!) Aug '63 to Feb '64 belong to to John and Oliver. Who was Capt. Little? William spent the entire war in EMM, Union, and VMM service. He was distanced from family at begining of the war though I'd think he likley knew what his Dad and brother were up to.
