Monegundis
Monegundis (Monegund, Monegundes) (died 570 AD) was a Frankish hermit and saint. A native of Chartres, she married and bore her husband daughters. When her daughters died in childhood, she decided to become an anchorite after a long depression, and after receiving permission from her husband. She founded a hermitage, consisting of a private room, at Chartres but later moved to a site near the tomb of Saint Martin at Tours. She acquired a reputation for holiness. There, she was joined by other women, and Monegundis devised a monastic rule that led to the founding of the convent of St. Pierre-le-Puellier.
Her feast day is held annually on July 2.
