Looking for information on Robert "Robin" Adair, b. 1878 in Gainsville, Hall Co., GA to Robert B. and Aline Moss Adair.Both father and son were dentists. The family moved to Atlanta where Robin married Leonora.Their children included Frances, Robin Jr., James and Benjamin, all listed in the 1920 Fulton Co. census. I cannot find Robin in the 1930 census and presume he may have died.I have located his father Robert, 80, in that census living with wife Mattie and four grandchildren. Anyone familiar with this family?
