HI from england.
some 5 years ago I did research on the 225 Dziks listed on the Ellis island immigrant site . As you know Poland was divided up in the 1790's between Austia, Prussia and Russia. Thus Polish US immigrants referred to these countries, not Poland as home. The Shtetlseeker site using Multimap, has superb MAPS giving huge detail. Radlow near Miasto in southern Poland was then in Austria, which stretched to now SOUTHERN Ukkraine. 3 miles SW of Radlow is Tarchaly Wielkie. 3 miles NW is Przbyslawce, where many US Dzik immigrants give as a home.Also asume Radow on Ellis site is Radlow.
