The Heretic's Daughter
Dava Sobel describes the correspondence to Galileo Galilei from his daughter, Virginia, who was a nun in the Convent of San Matteo, near Florence. Virginia, who took the religious name Maria Celeste, was a kind of apothecary in her convent, and she did her best to provide elixirs and pills to protect Galileo from the plague, along with weekly letters of news and encouragement.
