I can't seem to shake this. But, advise you of the CW Units file which contains info on persons who possess information on individual units.

Check them out at:

Subject: Civil War Units File CWUNITS New Version Available

Version 8.8 of the U.S. Civil War Units File (Sept. 27, 2006) is
available on the web and will soon be available from the Rootsweb
server. (See below for addresses.)

The Civil War Units File (CWUNITS) lists people who have information
on a unit, ship, or group (often rosters, battles, etc.) and are
willing to help others research it. Some are experts; most are
"just" helpful fellow researchers. If you see a listing for a unit
you are interested in, you can send the contact person email and share
information. There are also listings for battles, organizations,
counties, ethnic groups, etc.
