In 1067, shortly before his death, Ekbert I attempted to repudiate Immilla in order to marry Adela of Louvain, daughter of Lambert II, Count of Louvain and the widow of Otto I, Margrave of Meissen.[5] After Ekbert's death in 1068, Immilla spent some time at the imperial court with her niece Bertha, before returning to Italy.[6] It is possible that she acted as regent for her young son, Ekbert II, at this time.[7]
Immilla died in Turin in January 10, 1078. She is sometimes said to have become a nun before her death.[8]
