Unidentified group - schoolchildren?

I found this picture at my grandmother's (Floye Perry McGowan) house. She doesn't know anything about it, but said it probably belonged to her mother, Myrtle Christian Perry. The little girl on her knees at the left (in the dark dress) looks a lot like her.

It was taken in Laurens County (Dublin) Georgia or possibly Wilkinson County (Irwinton) Georgia.

I'd guess it was made in the early 1900's.

Here's a comparison:

Robert Christian Family

(Robert and Lenorah Christian>Myrtle Ivelina Christian Perry>Floye Perry McGowan>John Perry McGowan>Me)

I can't remember who sent me this picture, but it's too small to print, so I would love to find a higher-resolution version. This is of my great-great-grandparents, Robert and Lenorah (Dominy) Christian, and their children.

Robert (1878-1933) and Lenorah (1873-1960) are buried at Big Sandy Baptist Church Cemetery in Wilkinson County, Georgia.
