Oh no! :O
I hope you got it done on time!
There are a few sources that talk about two of Persephone’s children, mostly in the Orphic hymns, one that later Byzantine-era writings directly attributes to Hades but with no mention of a mother. However, you can read between the lines about each of the children and see that there’s a high likelihood that before the Greek deities were syncretically combined into a single pantheon that those children belonged to both Hades and Persephone.
