I would agree with that guess. It just makes sense that "the boss" would be central.
I have some photos of other family members, too, just not on this line. OLD photos.
I've asked the great-granddaughter and the 3-greats-grandson for the location of the graves, because there is no notation on the photo itself, and find a gave and billion graves have been less than helpful.
The Belvidere Cemetery has lots of the Totz family, but not, so far as I can discover, Axel and Ida.
