Will the real Aunt Peggy please stand up...

A back-of-photo conversation between Wathada and Cleffie.

(The red ink handwriting is mine.)

Here's a picture of  the real Aunt Peggy, with the Arnold family:

Photo L-R: Aunt Peggy, George, Adaline holding Etta, Annie behind John, John Henry holding Marlie.

Here's a picture that I believe may be the same woman as in the 2nd (greenish) photo above.

This is George Bullard's 2nd wife, Mary Morehead Robinson Bullard. I could be wrong, but in comparing ALL the family photographs, I think this is the most likely match.
