Margaret DETTER

This picture was found in my mother's things when she passed away. It is simply marked Margaret DETTER in the corner. I don't know if she is connected to our family or simply a friend.

Does anyone recognize this woman or the DETTER name? She may have come from Ohio or Illinois depending on the connection. If she isn't related I would love to get this photo to the family it belongs to.
