Most of you must be familiar with the 'Butcher of Paris',
Carl-Albrecht Oberg.
Unfortunately I happen to share the same last name with him, and as my family originates from Brunswick in Germany, (and there are not many Obergs in Germany, mostly in sweden) I was hoping someone had information on his direct family, as I would like to reassure myself that we are NOT related

A family tree, or some kind of record perhaps?
