However, firm information on this place is available only from the 11th century, when the monastery, with some property to endow it, was given by Landgraf ":de:Ludwig der Bärtige" of Sangerhausen or his sons Berengar and Ludwig to Hirsau Abbey, reportedly after the younger Ludwig had killed Markgraf Friedrich III during a hunt in 1065. After being incarcerated, Ludwig escaped. He founded Reinhardsbrunn Abbey near Coburg and possibly gifted his possession at Schönrain to Hirsau. Around 1100, abbot Wilhelm von Hirsau built the monastery, from which the monks served the whole region between Lohr, Gemünden am Main and Karlstadt am Main.
