Abbess, born in the tenth century; died at Cologne, 5 February 1015. She was daughter of Megingoz, Count of Guelders, and when still very young entered the convent of Saint Ursula in Cologne, where the Rule of Saint Jerome was followed. When her parents founded the convent of Villich, opposite the city of Bonn, on the Rhine, Adelaide became Abbess of this new convent, and after some time introduced the Rule of Saint Benedict, which appeared stricter to her than that of Saint Jerome. The fame of her sanctity and of her gift of working miracles soon attracted the attention of Saint Herbert, Archbishop of Cologne, who desired her as abbess of Saint Mary’s convent at Cologne, to succeed her sister Bertha, who had died. Only upon the command of Emperor Otho III did Adelaide accept this new dignity. While Abbess of Saint Mary’s at Cologne, she continued to be Abbess of Villich. She died at her convent in Cologne in the year 1015, but was buried at Villich, where her feast is solemnly celebrated on 5 February, the day of her death.
