David & Nora (Carr) Wilson of Knox County, Indiana

The back of the photograph says it was taken at Frog Pond in 1919, with which I am unfamiliar.
I do not know the lady on the left holding the baby.
Nora's husband Wm David Wilson is next and Nora on the right. They married 29 May 1901 probably in Lawrence County, IN, and lived in Bruceville, Knox County, Indiana. They did not have children. When he died in Washington Twp, Knox County, 9 Aug 1929, Nora was the informant and gave her residence as being in Bruceville, Indiana, which must be near Vincennes. She died on 17 Dec 1973 in the home of Dorothy Sheeks in Mitchell, Lawrence County, Indiana. Her obituary says she was a graduate of the Southern Indiana Normal College of Mitchell, taught school for 13 years in Knox Co, IN, and was a member of the Wesley Chapel United Methodist Church. She and her husband are buried in Sheeks Cemetery in Mitchell.

Perhaps David and Nora Wilson also owned a cottage at Frog Pond, and perhaps it too was in Knox County, Indiana where they lived. Does anyone know if that is where it was?

Also does anyone know the identity of the lady on the left and the baby she is holding in the picture?
