The village of Lobsens is located north of the town of Wirsitz, northwest of Nakel, which is west of Bromberg. These are all in the northern part of the Prussian Province of Posen. These would be their names on a historical map. Since they are all now in the country of Poland, a current map will show Lobsens as Lobzenica, Wirsitz as Wyrzysk, Nakel as Noko N. Notecia and Bromberg as Bydgoszcz. My great-grandparents Ludwig Falk and Anna Louise Leu were married at Nakel in 1850, so have done some map research in the area.
