Sorry not to have gotten back to you sooner...I haven't checked this section in a long time. I have seen "Nacsin" quite a bit in my searches, but not directly to my surname. Was your ancestor named Rosa? There's an obit from the 1920's in Minnesota on the internet with a Rosa Dudasik. I'll search thru my papers and see what I can find from Breza, Lokca and Nizna. Thanks
