The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 50
Of the Sisters and the Nephews of St. Patrick.
And the saint had three sisters, memorable for their holiness and for their justice, and they were pleasing unto the Lord; and of these the names were Lupita, Tygridia, and Darercha. And Tygridia was blessed with a happy fruitfulness, for she brought forth seventeen sons and five daughters. And all her sons became most wise and holy monks, and priests, and prelates; and all her daughters became nuns, and ended their days as holy virgins; and the names of the bishops were Brochadius, Broichanus, Mogenochus, and Lumanus, who, with their uncle, Saint Patrick, going from Britain into Ireland, earnestly laboring together in the field of the Lord, they collected an abundant harvest into the granary of heaven. And Darercha, the youngest sister, was the mother of the pious bishops, Mel, Moch, and Munis, and their father was named Conis. And these also accompanied Saint Patrick in his preaching and in his travel, and in divers places obtained the episcopal dignity. Truly did their generation appear blessed, and the nephews of Saint Patrick were a holy heritage.
