Hi!
Well, since I posted that, I've found out quite a bit. We don't have an August Bluhm (turns out the August is my great great grandfather A. C. Heitschmidt). My grandfather is Fred. His sibilings were/are Charles, Henry and Marie.
We're all in/from Indiana, not Minnesota.
I hope I didn't get your hopes up too much. I'm sorry!
Megan
