Eusebia of Hamage was a 7th-century Frankish abbess who led a religious community in what is now Wandignies-Hamage, France. Born in 637 to noble parents, she was the great-granddaughter of Saint Gertrude. Following the death of her great-grandmother in 649, the young Eusebia became the titular head of her abbey at age twelve. Despite facing significant family conflict and physical hardship during her youth, she remained dedicated to her monastic life, eventually serving as abbess for twenty years until her death in 660.
