About Lapa di Benincasa (Piagenti)
Lapa, Saint Catherine of Siena's mother, was about forty years old when she prematurely gave birth to twin daughters, Catherine and Giovanna.
Lapa had already had 22 children, but half of them had died. Giovanna was handed over to a wet-nurse, and presently died, whereas Catherine was nursed by her mother, and developed into a healthy child.
She was two years old when Lapa had her 25th child, another daughter named Giovanna.
