Mueller Sod House, about 1903
In front are Clara in the buggy, Anna (mother) holding Hulda, Anna, and Frieda (and the dog).
Back by the house is William with his team of horses and wagon.
This is the complete photo. See below for a zoom in on the people, house and horses.
From the shadows, I think the camera is pointing westerly, that is, we are seeing the east side of the house. Can anyone clarify this?
