Pam - You should plan to spend at least one day at the Georgia Archives in Atlanta. There you will find all Ga census records. If you find your people in 1920, for instance, you could check the GA death index, located at the Archives, for their death certificates. Then after you order the death certificate, you may find where they are buried. Also, you can probably easily find the two in their parents' households in the 1950 census. All Carroll County records are on microfilm at the Archives. You should also plan to spend at least one day at the Neva Lomason Library in Carrollton.
