Hi Jerry,
I found in "Slownik Geograficzny"[ Geographical Dictionary of the Kingdom of Poland...]published 1880-1902;
"Krzyz~ownica,in German Westfelde, village and manorial farm [folwark], 791 morg [+/- 800 acres], 6 houses, 77 inhabitants, 10 luterans and 67 catholics, 32 illiterates."

I know, that surname Sl~omin'ski is also noble surname from1659.

Cordially,
Wladyslaw
