Герман I
In 1122, his uncle Herman III of Reinhausen died in Formbach, and thereby the Counts of Reinhausen died out in the male line. As his closest relative, Herman I inherited Reinhausen and he also became bailiff of Reinhausen Abbey, which his maternal ancestors had founded. Later that year, his father died, and Herman I inherited Windberg and Formbach as well. He also became Count of the Leinegau.
