My name is Cornelia von Bargen and I live in Sweden in a town called Visby.
I saw your question on a forum about that you would like to know about the name von Bargen, well I can tell you as much as I know.
I guess you already know that it is a German name, it comes from the city, Hamburg and is one of the 3 most oldest names from Hamburg, so there are 8 streets in the city that are named after these names, and there is a street called " von Bargen street. As far as way back in 1502 there was a man who was so good in building harbours in the pole teknik, so because of him, Hamburg was able to be that big harbour city even though Hamburg is so far down in the country Germany. So he was made von Bargen, at first he only had Bargen for his surname. in other words he became aBaron. The family has been realy rich for many years, but most of the money dissapeared when the german money value crashed and a stamp would cost over 1 million mark, so if you were rich then, it all vanished.
I know that there has been a big clothes firm called von Bargen and they even had catalogs with clothes for sale. There has also been a big Ship builder, so a lot of ships before was all named for example..Ingrid von Bargen etc etc with diffrent first names. I don't know if any of these still exsicts.
So here in sweden it is only me and my family named von Bargen, my husband has taken my surname when we got married.
