Looking more deeply, it appears John died in 1853, and Terrell died in 1850. There appears to have been a brother Lenoir, born ca. 1808; Albert, born ca. 1813; Gaston, born ca. 1814; and William, born ca. 1812, or 1818. Although I haven't confirmed it, it has been reported that William appears as living with Tim in the 1850 census. There are indications Lenoir died in the 1880s, but I don't know if he was present in SEMO. I don't know where Gaston resided, or if he was alive at the time of the war. Besides Tim, we know that Albert and William were in SEMO in the 1850s. Tim, born ca. 1821, seems to have been the youngest brother in the family. In 1862, the Federal Missouri State Militia purged most of their officers older than age 45. That may have just been a consequence of needing to downsize from 14,000 officers and enlisted men down to 10,000 so that policy might not have carried on over to other branches of the armed forces. However, the ages indicated for the Reeves brothers would seem to be at the high end for entry into the army so another possibility may be that the /scout/Federal officer/Tim Reeves brother/ being referred to was actually a nephew of Tim, and not a brother. Be that as it may, it still doesn't hurt to cull through the files to see if any likely prospects from SEMO with the name of Reeves appear, be he a brother, a nephew, or some other relative.
