 Legend states that when Gerlach had done enough penance, water from the local well transformed itself into wine three times as a sign that his sins had been forgiven.He died shortly after, barely fifty and legend has it that the last rites were administered to him by the Saint Servatius himself.The Order of Premontre (Norbertines) claims his as one of theirs, due to his "rough white habit", and has him on its liturgical calendar as a "Blessed"

Gerlach is a male forename of Germanic origin, variations of which exist in many Germanic and Romance languages.
