Love both of them, of course
Pandora moreso, being my favourite name. There's strength, fight, sass, and mischief all bundled into one.
Persephone's is elegant, and beautiful, in a dark, floral way, so great imo. Neither connection bothers me. Greek mythology holds a lot of interest and joy for me, so the connection is positive, even if the myths themselves are not. If anything
Pandora's commercial associations are more an issue (not a big one though).
Middles for
Pandora, I think short, fun, and feisty;
Pandora Clio,
Pandora Ezri,
Pandora Kitty,
Pandora Sylvie.
For
Persephone I'd go whimsical, maybe wordy;
Persephone Alice,
Persephone Winter,
Persephone Iris,
Persephone Amalia,
Persephone Wren.
