Heirs of Julius LUCZNY

We are searching for the LUCZNY family who in the 1910 – 1930 period lived in house number 17 in Wehowitz (now probably Wiechowice in Poland). 
All we know of the family at the moment is that it consisted of Julius LUCZNY Senior, a farmer, and his son Julius LUCZNY.
Julius had a sister Marie LUCZNY who also lived in Wehowitz.
We do not know what happened to the family in the 1940’s, and are now searching for their traces.

Do you recognize any of these names?

Can you guide us in any way?

If you have no information, do you know of anyone else, anywhere, where we can ask?
