Marilya Jaddo was the wife of Vocator Urza Jaddo, an official of the Centauri government. He and Marilya had been married for many years at the time of his death in 2259. After Urza's death in the Morago at the hands of Londo Mollari, Marilya - along with the rest of House Jaddo - were absorbed into House Mollari and thus protected from the resolution passed against him by the Centaurum, which had been Urza's plan all along. It is unknown if she was still alive in 2278, but her neice and nephew - Lyssa and Lucco Deradi - were in the care of their governess, Senna Refa, also a ward of House Mollari.
