Buffao, NY Lange family: Gus, Emma, Albert
I have an old photo family album. There are pictures of a Lange family from Buffalo, NY. I'm not sure if these were friends or family. I'd be happy to share the photos.
A picture taken in Chicago Aug 1912 is labeled: Gus, Mother Lange, Father Lange, ?, Emma, and Albert. The ? is another son slightly older than Emma. Gus appears to be 16, Emma is about 5 (hard to tell though), and Albert is about 10.
I have a few others taken a couple years later. Emma is about 10 in that picture. Unfortunately, the parents names are never given.
