I now have additional information about the persons in the subject.
Jürgen Friedrich Schley was born in 1710, in ?, died 18 October 1772 in
Pieverstorf near Ankershagen.
He was married to Hedwig Christine Schock, born 1698, in ?, died 1 June
1772 in Pieverstorf near Ankershagen.
They had no children.
In 1763 Jürgen Friedrich was the owner of Schloss Pieverstorf and he
and the maid Marie Dewitz, got a son Johann Friedrich who was born 29
May 1763 in Pieverstorf.
I'm looking for more information about Jürgen Friedrich Schley, Hedwig
