Floods / Margaret of Hungary, 1242–1271,
Feast Day: January 18

A princess whose parents promised her to God in thanks for stopping an enemy invasion, Margaret refused to leave the convent where she was placed. As an act of penance, she refused to wash and tended the hopelessly ill. Her father built her a convent of her own on an isle in the middle of the Danube River. Whenever it was threatened by flooding, she protected it with prayer.
