I checked the Supplements today, no joy. There are only a few Missouri reports shown for this period. All were derived
from the Rebellion Records, so that would be no place for further checking.

As to Lt. Col. Boyd, there were no records of Marcus of the Green County Home Guards. There were some 14 hits for S. H. Boyd, however these were all related to the 24th Missouri dated mid 62' and later.

Couldn't find anything on Capt. Robinson either.
