I am happy to say that we already have one ID on this woman:
Tennessee v. John T. Scopes Trial: Andrewena Robinson Davis
by Smithsonian Institution
She is apparently the daughter of F. E. (Frank Earle) Robinson, in whose drug store the idea to instigate evolution case was formulated! We received a note from her granddaughter. This is the second time a granddaughter has reached out to us to help id a person in the Smithsonian Archives!
Please see the blog post about the unidentified photos here - http://blog.photography.si.edu/2011/07/13/crowdsource-this-please-scopes-trial-photos/, and the set of photos on the Flickr Commons here - http://www.flickr.com/photos/smithsonian/tags/unidentifiedscopes/.
Any help in identifying these people would be great!
