I think Cora is Persephone. From the wikipedia page:

"In  Greek mythology,  Persephone ( / pəˈsɛfəni / ,  per- seh -fə-nee ;  Greek:  Περσεφόνη ), also called  Kore or  Cora( / ˈkɔəriː / ; "the maiden"), [n 1]  is the daughter of  Zeus<span style="font-weight:normal;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;line-height:22.4px;"> and the harvest goddess  Demeter<span style="font-weight:normal;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;line-height:22.4px;">, and is the queen of the  underworld<span style="font-weight:normal;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;line-height:22.4px;">." -   https://en.wikipedia.org/wiki/Persephone

Otherwise, based on what Sunny's Wig said, I think Zelena could be Persephone.
