Bertilia was a 7th-century noblewoman from northern France who dedicated her life to religious service. Although she initially desired to live as a hermit, she eventually married a nobleman named Guthland. The couple lived together in chastity, dedicating their wealth and time to acts of mercy and hospitality for the poor. Following the death of her husband, she donated much of her property to the church and established a monastery in Artois, where she eventually spent her final days.
