[3][4] After the death of Prince Jordan I of Capua, the suzerain of Gaeta, the Capuans and Gaetans rose in rebellion.
Jordan's successor, Prince Richard II, was forced to abandon Capua for the family stronghold of Aversa, while Duke Raynald of Gaeta had to flee Gaeta for his family's rural stronghold at Pontecorvo.
[4][5][6][7] Shortly before 1100, Gualganus married Marotta,[8] a daughter of Count Ranulf I of Caiazzo and his wife, Sibylla.
[5] Gaeta is next found in the hands of another Norman, William de Blosseville, who may have ousted Gualganus rather than wait for his death.
Pontecorvo passed to his widow, sister of Count Robert of Caiazzo and cousin of Prince Richard II.
