Oops! Maybe MD, not Britta

I collected all the photos of Britta and Mary Drucilla in one place, edited them to a similar size and shape, and compared them. The comparison leads me to believe that the woman my ggrandmother Lizzie gazes so lovingly at in the original is her own mother Mary Drucilla McGuire Edins. 

The pictures are below. What do you think?

Young Britta

Britta about 75

Older Britta--Label on photo is "Granny Flynn."

This has been identified as Mary Drucilla McGuire Eddins, age about 52

This photo is labeled "Mary Drucilla, Grandmother Edins."

Guess who???
