You have been very busy on Ancestry.com what other records are you seeking other than what you have collected on ancestry. Did you try looking for pension records as well. I'm not seeing any attached CSM records attached to a George M. Harvey except from what you have already from South Carolina on George Harvey.
Dear Mr. Harvey,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Carded Records Showing Military Service of Soldiers Who Fought in Confederate Organizations in the War Department Collection of Confederate Records (Record Group 109) that includes a file for Harvey, George - Holcombe Legion G-I. These records have been digitized and are available using the Catalog.
We also located the Carded Records Showing Service of Military Units in Confederate Organizations in Record Group 109 that may include a card for the Holcombe Legion. The cards contain the names of officers, historical data about the organization, and a record of its achievements as transcribed from the "record of events" section of the Confederate muster rolls. For more information about the non-digitized records, please email the National Archives at Washington, DC - Textual Reference (RDT1) at email@example.com.

South Carolinian Confederate veterans and widows were eligible to apply for a pension to South Carolina if he was disabled or he/she was financially needy. In your letter to the South Carolina Department of Archives and History, please include the Confederate veteran's name, his widow's name, the unit(s) in which he served, and the counties in which he and his widow lived after the Civil War. Beginning in 1889, the SC Comptroller began publishing lists of such veterans receiving pensions in his Annual Report. From 1919 to 1925, South Carolina granted pensions to Confederate veterans and widows regardless of financial need. These files are arranged alphabetically. Pension application files are typically one sheet of paper with writing on both sides.
We hope this is helpful. Best of luck with your family research!
