Thank you very much, Barbara! I didn't have the cemetery information, and I appreciate you finding it for me.
I just emailed the congregation to see if they might have any information on where in Germany Adolph W. came from.
I rather wonder if in 1910 a neighbor answered the census taker for the Selzes. There was a big extended family of Selzes in Chicago, Illinois, and there WAS an Adolph or two among them. They owned the Selz Shoe Company and were quite well known.
I don't know if they're any relation to my Selzes, though. I've not found any link so far.
Thank you again!
