This picture was taken 100 years ago. It was taken in Zanesville outside of their home when Rev. Martin Brueggeman was visiting. Martin had already moved to Memphis and must have been back in Ohio to visit his brother, Ernst and family.
Selma was really selective when she labeled her pictures. Sometimes not all the siblings are identified. In this case, the young lady on the lower right wasn't identified. In my opinion, she looked a lot Louise but I am not sure.
