So, we’re not related.
As to the Donauschwaben, I just finished this book, published in February about the Banat, the history of the region, the Donauschwaben settlements and the locals.https://www.sup.org/books/history/banat-temesvar
It’s an academic book, as you can see from the price, written by a professor and full of footnotes. I found it very interesting, and it fills in the political background of the Hapsburgs and the Banat going back to the beginning.
