 Later chronicles written by Johann Koelhoff the younger in 1499 mention that Archbishop Warin of Cologne (976-985) had renovated the Church and placed Minnborinus of Cologne in charge of it (see Hiberno-Scottish mission).Ebergar (985-999) wrote that with donations in 989, the Church was transformed into a monastery for Benedictine monks from Ireland.They included Kilian of Cologne (died 1003), Helias of Cologne (died 1040), Aaron Scotus (died 1052), and Molanus (died 1061).
