Which of these Roman Goddesses was associated with the underworld and spring at the same time?

It's a sad story, with poor Persephone doomed to spend part of the year in the underworld with the guy who abducted her, just because she ate some pomegranate seeds.

I've studied the Eleusinian Mysteries for 35 years. The Mother and Daughter and their rites were present in Greece long before the Hellenistic period. They spread and were adapted all over the Mediterranean.
