The Ellis Island site gives the place of origin of a friend's grandparents as MADLIBORG, RUSSIA. They were actually Poles, apparently in the Russian section of 1912 Poland. However, Madliborg sounds more German than Russian, plus a Google search on Madliborg turns up nothing. I realize that the Ellis Island site often makes transcription errors, but I'm looking at the manifest and it definitely seems to be Madliborg. In another section (address of relative or friend) it seems to say Madliborg Warsaw. On entries for other immigrants I see other Polish towns, also followed by Warsaw (example: Sompolno Warsaw, Rosno Warsaw...maybe Roznow?). Looking at lists of Polish towns, Modlibórz seems to be closest, but I think it was in the German area, not Russian. If German, I wonder if its German name was Madliborg/Madliburg. Anyone have any ideas?
