John,

I have found in one old map that Niesky should be German name for Jawor (and it is true that German name for Jawor is Jauer as well) and I know about Niesky in Niederlausitz as well. So, right know when I prove all of available Information I am able to say I am not sure. Yes, it seems that Niesky could be that town in Niederlausitz most probable.
