Dear Karl, A cousin of my grandfather tried to clear up a little bit the confusion which exists about the name von Bargen/von Bergen. He wrote that there are different families who have this name. My one is characterisated by being mostly mentionned until 1700(+/-) as v. dem Berge/ v.dem Barge . Bargen(Barge) is only the northern german dialekt of Bergen(Berge) which both mean "Mountain". Vom Berge also was found a few times but very rare. So that the today living "vom Berge" are propably another family. I hope I helped you a little bit.
