Very much so, but more on my paternal side than my maternal side. But I have it in both.
My paternal grandparents were both very recent immigrants. My opa was from Austria and my oma from Germany. Or that is what I told - little did I know how complex the situation was. Where my oma was born was Germany at the time, though is now Poland. My opa's ancestors' original area where they were in the late 1800s is now, I believe, Serbia. I don't speak or read German, either, so I'm at a loss on research on this side of the family. My opa's surname was Metz, my oma's was Palnau. There is also Schmidt, Henke and Bukowska as other surnames I've managed to find. The Metz side has a family history booklet that some relatives put together, but I'm unsure if this lists sources or not.
Also, my om'as father was drafted into the German army at the very tail end of World War II. He did not return and was listed as MIA - his brother said that he was blown up by a bomb. The official records for missing German troops says that he was officially listed as MIA on January 1st, 1945. He was in his 40s at the time, certainly not an ideal age for a soldier but they were likely desperate at this point.
My German heritage on my mother's side is further back. Through my maternal grandfather there is some potential that a branch of German immigrants from the 1700s mixed in with the line of Irish immigrants from New York that he descends from. This would be through a woman with the surname Meyer/Meier, but I have yet to find proper sources for her parentage beyond a few other family trees so I am taking this with a grain of salt.
The Prussian through my maternal grandmother's side is well documented, however. Te Bonins and Glomskis originally came from West Prussia. They both seem to be Catholic families. Other surnames are Schultz and Grubich. (Glomski always seemed very Polish to me, however, so I am unsure. Bonin I also tend to find more with France/Quebec, but it is definitely documented that this particular line came from Prussia.) Censuses for these family members either list themselves as Prussian, Polish German, German or Polish. They immigrated in the mid 1800s and settled in Wisconsin.
