Researching my GNOSS ancesters in Ostpreussen. My great-grandmother was Marie GNOSS born 26 Jun 1863 & baptized 19 Feb 1864 in Bartoszyce, Warminsko-Mazurskie, Poland, married 06 Jun 1882 in Heimthal parish of Zythomyr area of South Russia/Ukraine. Her father was Carl GNOSS born 03 Oct 1840 in "Bolken"/Borken/Borki, which I believe is Borki bei Bartoszyce, Warminsko-Mazurski, Poland. I see you listed the surname GNOSS, and although your post is from 2000 I am hoping you are still out there searching!
There are other GNOSS in Spittehnen, Bartenstein, Ostpreussen, Preussen which = Spytajny, Bartoszyce, Warminsko-Mazurski, Poland.
