Originally I thought this might be from one of the Lane family reunions, but now I think it might be the Campbell family. The man to the far left looks like Lee Campbell, the woman beside him is my great-grandmother, Roma Campbell Lane. At the end of the table (on the left corner) is my grandmother, Rhodees Lane Orr, holding my father, in the black dress beside her is Mary Price Orr (who is my great-grandmother), then it looks like my grandfather Price Orr or his twin brother James. Behind Mary Orr is, I believe, George and Lois (McKay) Watson. If you can confirm these people or name the others please share!
