Another legend says that Boniface stood on the top of the Hülfensberg and said, "Wann wird endlich Frieden schweben über dieser schönen Aue" ("when will peace at last hover over this lovely forest?"). Folk etymology derived from his supposed words the local place names Wanfried, Frieda (in Meinhard), Schwebda (likewise in Meinhard), and Aue (in Wanfried).
