I wish there wasn't so many names associated with this story. It would make my job of researching what happened to Violet much easier!
I too found the same possible death dates for Anna Buehler that you listed:
F/W UNK 6029902 1933-11-14 COOK CHICAGO 33-11-16
F/W UNK 0019950 1948-07-05 COOK CHICAGO -
I will have to order the death certificates to see if either of them mention Violet - but if they don't, perhaps you are right and I should try to find the marraige license for Violet in Cook County.
Thanks for the immigration records on Adel and William. Yes, Adel was married to Frank Bobzine (sp?) before, and both John and Violet are from that marriage. According to one newspaper article I read, William did not even know Violet existed when he married Adel! He only found out after she ran away from Mrs. Buehler. The article also stated that it was believed Frank killed himself in NYC, but it did not give a year. It also stated the police thought he might be still alive, and had something to do with her running away, though it was never proven that I could see.
Another articles lists Barbara Peters as "Violet's old grandmother" who continued to remember the child, and set out "on a search for her." She found her in Mrs. Buehler's home. I have no idea if that would be Adel's or Frank's mother, but I assume it was not Mrs. Buehler's mother (?).
If I don't find a marraige cert. for Violet, my search may end here.
Thanks for all your help!!!
