Does anyone know whether a detailed genealogy exists for the von Frankenstein family? I have seen information about prominent representatives such as the Frankish knight Arbogast von Frankenstein in the 500s, Sir George Frankenstein in the 1500s, and others, but I have never seen a full-fledged genealogy, generation by generation. In the course of researching my Reubling ancestors [Elizabeth Reubling married Johann Georg Stumpf in Darmstadt, Hessen, Germany, in 1699], I was informed by an e-mail correspondent that many years ago he had seen on a Reubling genealogy chart a reference to the marriage of a Reubling to a daughter of one of the barons von Frankenstein. In view of the fact that the 13th-century Burg [Castle] Frankenstein is perched atop a mountain just outside Darmstadt, this alleged marriage could have some basis in historical fact. So, again, does anyone know where a detailed von Frankenstein genealogy might be found? Thanks in advance for any help or suggestions!
