Dear Friends,
Thank you for your assistance.
As the result of your help, I was able to find a map with Millbrook Township listed. I know that there was a substantial community of African Americans, including my grandmother's family of Gants, living on Whiskey Road during the 1910 US Census. I believe that my next step is to look at subsequent censuses to see what happened to families who lived around my grandmother in 1910. Also, see if Millbrook Township is used on subsequent censuses. If not, when did it stop being used and why. Lastly, maybe there is a department in the Aiken County City Hall that can assist me.
