The back of this photo says "Mrs. Anna Porter, R. R. 2, Moundville, MO" I don't know much about a Porter family at Moundville. There was a Porter Schoolhouse east of Moundville in the 1880's. By 1909, there was an S. J. Porter listed on the Lone Star Phone Line about that time, there was a Roy Porter joining the Methodist Church.  So I don't know if these ladies are related to any of these or not. I am guessing that this might be mother and daughter.
