St. Adelaide of Burgundy
This
impressive 10th-century saint really understood family conflict. She was betrothed at 2, married at 16 and became a widow soon after. She was then imprisoned for refusing a marriage proposal but was rescued by King Otto of Germany, with whom she went on to have a successful marriage for 20 years. After Otto's death she went through one family conflict after another and finally retired to a monastery she had helped to build. Among the turmoil, she was a mom to five, helped the poor, and built monasteries and convents.
