In 1600, Galileo met Marina Gamba, a Venetian woman, who bore him three children out of wedlock: daughters Virginia and Livia, and son Vincenzo. He never married Marina, possibly due to financial worries and possibly fearing his illegitimate children would threaten his social standing. He worried the two girls would never marry well, and when they were older, had them enter a convent. In 1616, at the San Mateo Convent, Virginia changed her name to Maria Celeste and Livia became Sister Arcangela, when they became nuns. Maria Celeste remained in contact and supported her father through letters until her death. No letters from Arcangela survive. His son’s birth was eventually legitimized and he became a successful musician.
