On this day, we commemorate St. Eusebia, who was born c. 637, and who died c. 680.
Eusebia was a member of a Merovingian family of saints. Her great-grandmother, St. Gertrude, Abbess of Hamay, was the daughter of King Theudebald, King of Austrasia.
Eusebia's parents were St. Adalbald, Count of Douai, and St. Rictrude, a Gascon heiress who, after her brothers murdered her husband, became Abbess of Marchiennes.
Eusebia's brother was St. Maurontius, and her sisters were St. Clotsendis and St. Adalasenda.
Her aunt was St. Bertha, and her cousins were St. Gertrude and St. Deotila.
Eusebia's godmother was Queen Nantilda, a consort of Dagobert I, King of the Franks, whose tomb is at the Basilica of Saint Denis. Nantilda gave her goddaughter "the fine estate of Verny, in the neighbourhood of Soissons".
Eusebia was eight when her father was murdered by Rictrude's brothers. She and her sisters went with Rictrude to the double monastery of Marchiennes, but Abbess Gertrude asked Abbess Rictrude to give Eusebia to her. She adopted the child and made her heiress of her monastery of Hamay.
Gertrude died, and Eusebia, aged 12, became Abbess.
