They wrote me back from Worms and said they cannot help me find records on my grandmother, Berta Haller, since I do not know her date of death. I'm anxious to get information on her because I know she also had a son before she gave birth to my mother and gave her up for adoption. So it's possible my mother's half brother, my uncle, is still alive and living in Worms. Although I doubt he knows my mother even exists.
If you can think of any other place that would have records on marriages and deaths in Worms I would be grateful.
