Adalsinda or Adalsindis of Hamay and Eusebia of Douai, were 7th-century Columban nuns, who were sisters from a prominent Merovingian family; Eusebia became an Abbess. They are venerated as saints in the Catholic and Eastern Orthodox Churches.[1] Their parents were Richtrudis, a Gascoigne-Basque heiress, and Adalbard I of Ostrevent, a Frankish duke of Douai. Both mother and father are also recognised as saints,[2] as are another sister, Clotsinda, and a brother, Maurontius. They are especially venerated in Northern France and Flanders.[3][4]
Eusebia's commemoration is on 16 March; Adalsinda's feast day is 25 December, around the date of her death, by tradition "during the solemnities of Christmas".[5]
