There are a number of things you can do to memorialize your ancestor's war record, for future generations.

Unless you've already done so, start a subscription to Ancestry.com. You can enter his name, vital dates, war record etc. as a permanent record that can be easily shared with other researchers.

Compose a biography on your soldier with documented sources and donate a copy to the Georgia Dept. of Archives & History in Morrow, GA. Ask them to place it in the 5th Georgia Infantry file of their "Civil War Miscelleny" collection. At some point they will microfilm this material. Copies could be placed with the Georgia Historical Society library in Savannah; the Genealogy Room of the Washington Memorial Library in Macon; and the genealogical library operated by the LDS in Salt Lake City, Utah.

This same biography could be placed with the historian @ Chickamauga National Military Park for their regimental file; as well as the United States Military History Institute in Carlisle, PA.

Unfortunately, I'm not aware of anyone seriously working on a much-needed 5th GA regimental history, which would hopefully
include a roster not copied directly out of Lillian Henderson's error-filled infantry roster of the early 1960s.

Robert K. Krick did a masterful job with his "Gettysburg Death Roster", listing all the known Confederate dead from that battle. Perhaps one day someone will do a similar work for Chickamauga's Confederate dead, or just the dead from the Georgia commands' of that September 1863 battle.

Perhaps the SCV has a database you could give information to.

Sincerely,

Greg
