The wedding took place before January 998, when Emilia appeared with John at the monastery of Saint Nilus the Younger.
The Roman Emilia's politics leaned strongly towards support of the pope and the Lombards against the Byzantine Empire.
In 1012, she allowed Dattus, a Lombard rebel, to garrison a tower on the Garigliano, in Gaetan territory, with papal troops, supplied by Benedict VIII.
In 1027, when Duke Sergius IV was forced to flee Naples, Emilia gave him refuge, for John V was his nephew.
She died early in 1036, when her son Leo donated a house to the monastery of S. Giovanni di Felline in her memory.
