Louis Strohacker is my GG-grandfather. He was married to Christiane Schladoer. I have Louis' death date as March 6, 1927, but I am in the process of confirming this. His daughter was Elsa Strohacker, and married Hubert Heinen (my G-grandfather) in 1900.
I can probably track down some of Oscar's lineage if you are interested.
What other information are you looking for? Do have any background on Louis Strohacker or his ancestors? Do you have any information about his immigration/ timeframe/ port?
