No. On all the documents I have for my grandmother, the spelling of the village is Kropiwki. It is SW of Podedworze and Rusily. I checked through google maps and it is still there. Also, my grandmother got married to someone from Rusily and the marriage certificate also confirms where she was born and lived prior to her marriage. Thanks for asking and double checking.
I heard something about them. They were a family of peasants, who were known for their uncivilised behaviour at local hostelries. Nikon was known for drunken brawls, and his language was said to be very primitive and on the level of a 7 year old. He apparently would do a day's labouring, then would go out and get drunk. They moved around a lot, probably as a result of his penchant for violence.

Wieczorek is a very popular surname. And the villages you mention seem pretty small. It's hard to say if any Wieczoreks still live there. There might be some in neigbouring villages but it's hard to say if you're related. It was over a century ago with two world wars in the meantime.
You can try googling the surname + the name of one of the places you mention. It's Uhnin, I think. And Zaliszcze and Siedliszcze seem to be two separate places. All of the places you mention are in Lublin Voivodeship.
