In the book, History of Holte the name Stolgeb�hr appears on page 65. I don't know if its a town or a surname. The name Gelert does not appear, nor does Burchard, (to me those names sound French, perhaps from Alsac?), however, a name perhaps similar to Burchard appears as, Buricken page 33, Burken on pages 81, 97, 101, and Buschen on page 95. There is no Freckmann, but the name Focken appears on pages 55, 92.
Holte is in the Emsland area. Largest town nearby would probobly be Meppen. Its close to the Neitherlands.
