And by the way, there is a professor in the University of Lodz whose interests were the immigrants from Hesia and Baden. I know him a bit. He has written a very detailed and interesting text about the procedures of what were happening with all the people from Germany in ~ y.1830 which came to live in Poland next to Lodz. The text is based on two villages placed appox 6 km from Mikolajewice.

The text is in polish, however it is easy to put it all to google translator.

That text also explains why Siegwarts become Zygwarts... All the newly come people had to sign a contract. The notary who was preparing the contract changed all the names to what he was hearing.
