John XI
Allegedly the son of Marozia and Sergius III, John was born c. 910 in Rome and was made pope in 931. After the marriage of Marozia to her brother-in-law, Hugh of Florence, John's half-brother, Alberic III, imprisoned their mother in the Castel Sant' Angelo and confined John to the Lateran until John's death in 935.
