Annie,
We have that book and I have poured over it. There are some of the same first names in the family, which could be a clue. I have tried, unsuccessfully, to contact the family, and I will have to try again when I get back to this side. The problem is that my husband's surname was changed and my husband seems to remember it had nothing to do with Stahl (like Stahlberg, Stahlstein, etc). No one seems to know what it was though. His gr grandfather was in England for a few years as Harris Stahl, and he had siblings over here I believe, who used the same name. Maybe it was originally Schacht. My father-in-law's sister thinks Al and her father were maybe second cousins or something. My FIL remembered Al coming to the house one day in Brooklyn to visit his dad and what a thrill that was. I will have to scan in pictures and show the resemblance. It is uncanny. I would love to find the connection.
