Gross Boschpul in the former Prussia (German) or Pomerania area of Northern Poland is now Bozepole Wielkie, Poland, since the end of World War II. My paternal surname left this former part of German Pomerania in the year 1865. The river that goes nearby is called Leba. Here is a little information on the river and the area.
