Have you tried at polish site like https://genealodzy.pl or facebook group https://www.facebook.com/groups/GenealodzyPL/?ref=bookmarks ???
Hi: Just did a sample test of Chalupka and found it in Lublin, Swietokryski and Maloposka. It's pretty wide spread. Saw some Chalupka's in the Parish Registry in Gdow recently. Name is familiar to me because it's the last name of an old friend, but he was Serbo-Croat by upbringing. Seems to be a common Slavic name. You might also try two online sources that you can search using last name. They are both based in Poland:
http://geneteka.genealodzy.pl and http://regestry.lubgens.eu. They offer English as a usable language rather than Polish if that's a concern. Good Luck.
Anyone feel free to join the new project i created called "Trybus family in poland". It is for Trybus family history and helping other people figure out their Trybus ancestry. Feel free to join, work on other people's trees, add documents, add pictures, ask questions, provide info and videos, and work on your own trees.
Please Join!
