Writing a novel set in XVII Century Poland; Input Requested

Hi there! So like the title says, I'm writing a novel in which a large part of it is set in Poland the 17th century. If you can, would someone be able to help me figure out some made-up names for Polish villages and perhaps check the grammar of the Polish sentences I've used so far? So far I have

Czy to twój zamek? (Is this your castle?)
and
Nie. Ten zamek należy do mojego ojca. (No. This castle belongs to my father.)

Your Polish sentences are ok.
As for names of villages, anything with Wólka (=hamlet) will do. There are also tens of places called Kamionka (from kamień-stone, rock), Zalesie (behind the forest, Dąbrowa (where oaks grow) or simply Nowa Wieś (New Village - apparently the most popular name with 133 villages called like that). Names derived from from first names like Janów, Józefów or a real village but you'd have to do some research.

Remember that the 17th century was one of the most turbulent times in the Polish history - lots of conflicts and wars.

The sentences are correct, but would they be understood / valid in the 17th century? Probably they would get the meaning but language usage was probably a little different than it is today.

I doubt anyone in the 17th century would say that. I think they would have said: "Ten zamek jest mojego ojca". The phrase "należeć do" seems to be way too modern.

Also, you may ask: "Czy to Waści zamek?" with 'Waść' corresponding to the modern form "Pan".

what about waćpan?

I'd expect they would use more shortcuts (rather than "Ten zamek należy do mojego ojca" it might be something like "Ten zamek moja ojcowizna" :)

Yes, of course: "Czy to Waćpana zamek?".

"Czy to zamek Waszmości?" - will do as well as another one: "Czy to zamek Waszeci?".

Reading the Trilogy by Sienkiewicz should help.

Personally, I hate it. To me, Henryk Sienkiewicz was the 19th century version of Ilona Łepkowska ...

You seem to agree with my Polish teacher. Still the dialogues there are what Polish people think Polish sounded like in the 17th century.

A Novel Set in XVII Century Poland and Eastern Europe

So I just published a novel about mercenary company that tries to stop a Polish lord from restarting Zygmunt III's war with Gustavus Adolphus. There's sword fighting, romance, and winged hussars involved!
