I am also doing research on this same family. Your notes on searching are much appreciated. I am looking for information about Alois Thurmer (worked at the Tobacco Factory) married to Mary Uhlig who shares the same father Leonard Uhlig you outlined in this post. My great-grandmother was Paula Thurmer (daughter of Alois and Mary) who became a Sturm by marriage after coming to the US.
I have done my best to look through the books but have yet been unsuccessful. If you are willing to offer any assistance I would appreciate it.
