St. Jean and Erlach on the lake of Biel
His two daughters Anna and Agnès were also called to a religious life and would themselves enter the convent of Gnadenthal (Val-de-Grace) in Aarau (founded in 1270 and secularized in 1802). Agnès would become its abbess and in recognition for her saintly life would be beatified in 1405.
A good friend who pens the blog Three Hundred Words raised an interesting question, "Which Pope beatified her?" During the Western Schism in the Catholic Church (1378-1417), there was a Pope in Rome and an Antipope in Avignon. Agnès could have therefore been beatified by either Pope Innocent VII of Rome, or Antipope Benedict XIII of Avignon. If she were beatified by the Antipope her blessedness is probably not recognized by the church.
