With first wife, Caroline Reichert; 1st child, Louise, on the right; 2nd child, Emily, on the left.

Location; Based on the photo of Emil Falk in uniform, this is clearly the rear of 2480 W. Medford Ave., Alvin Falk's house.
The Date Estimate: The strongest determinant is that the three children prefectly match Alvin Falk's children.
The Man: Estimated age: 44. DOB 1853. He bears a strong resemblance to Alvin Falk (1860 - 1944) but seems a little older.
The Older Woman: Estimated age: 45. DOB 1852. She is nothing like Alvin's very-thin wife, Bertha. She remains unidentified.
Children: are prefectly consistent with the three children of Alvin Falk and Bertha Wilke; William, 9; Eleanora, 4; Emil, 11.
The Younger Woman: Estimated age: 28. DOB 1869. She exactly matches Bertha (Wilke) Falk, Alvin's wife, but appears too young. Another possibility is that this is Minnie Wilke, Bertha's younger sister and Eleanora's biological mother who would have been 26-27 at the time.

The day after the wedding. They are annotated as Eleanora, Emily (Barbaras) Haas, Klara, (Loretta) Frieda, Louise. I believe that the correct order is: Eleanora, Emily (Barbaras) Haas, Klara, Louise, (Loretta) Frieda. Louise's identity is unknown.
