A family of Heebner's came to America to seek Religious Freedom. Some were part of a group called the Schwenkfelder Families. These families came from Silesia Germany to Pennsylvania from 1731-1737.
Silesia was an area of Europe which is now in southwestern Poland. Germany ceded this province to Poland after WW II. The area borders present day Germany and the CzechRepublic.
The founder of the Schwenkfelder Church, Caspar Schwenckfeld, was born in Ossing, Silesia, which was changed to Ossig (Osiek in Polish),and is still a small town outside of Lubin, Poland, which is outside of Legnica (Liegnitz in German), Poland.
