Saint Sadalberga (or Salaberga) (died 665) was the daughter of Gundoin, Duke of Alsace. Cured of blindness while still a child by Saint Eustace of Luxeuil, she was twice married, first to a man who died after two months and then to a nobleman, Saint Blandinus, by whom she had five children, Saretrude, Ebana, Anstrude, Eustasius (died in infancy), and Baldwin. Two of these became saints, Saint Baldwin (Baudoin) (feast day October 16) and Saint Anstrude. Her brother was Saint Bodo (d. 670). After some years, she and Blandinus agreed mutually to separate and assume contemplative lives. He became a hermit and she went into a nunnery at Poulangey; Salaberga was subsequently foundress of the convent of St. John the Baptist at Laon. She died there c. 665.
