Yeah, I have exhausted the easy things to try to find out more about Granny’s mother Louisa Wolff. The only record I can find of her maiden name that is definitely her is the marriage record to Theodore Bruns. She was born in 1874, but I can’t find her in the 1880 census. In the 1900 census she is married, so we know this is the right Louisa, and it says she was born in MO and also her parents were born in MO. So if that’s true, they should be in MO in 1880, most likely. There are some possibilities, including an adopted girl with the same name and the same age, but without her parents’ names or more information, there’s no way to know for sure. And unfortunately, she died young, only age 33 in 1907, before MO started issuing death certificates in 1910, so that is no help either. I may have to trace all the Wolf/Wolfe/Wolff/Wulf/Wulfe/Wulff lines in MO to see if I can figure it out by process of elimination. But that is a huge job that will take a long time, so I’m putting Louisa aside to see if I can make some progress on other lines instead.
