I know its years later but I was wondering if you found out any info on Robert Eberhart. I was just researching my family tree and saw your post. It stood out because the Eberhart you were looking for was black (african american). I am also and just found out that my family is from Oglethorpe from a census record from 1910. My greatgrandfather's name is also Robert but he was born in or around 1889. His fathers name was Nathan Eberhart. Nathan was born in 1855. Just thought that we may be related. I haven't found anything prior to the record on Nathan.
