St. Adalsindis was born to Sts. Adalbald and Rictrudis. She entered the convent at Hamayles-Marchiennes, near Arras, France, in the early seventh century. Her sister, St. Eusebia, was the abbess there. Their other sibling was St. Waldalenus, who founded the monastery.
She peacefully fell asleep in the Lord in 680.
