In 1984 to 1985 (roughly when he was 17~19), Diavolo met Donatella Una, who was vacationing in Sardinia when they met. Donatella fell in love with Diavolo, who was under the assumed name of "Solido Naso", and they interacted enough to sleep together and have a daughter named Trish Una, whom Diavolo was never aware of. During this period of time, Diavolo told numerous lies about himself, all of which Donatella believed, and when they departed, Diavolo made a promise to return and never carried through with it.
