Stephanie King isn't a name that immediately rings a bell for me in mainstream entertainment, but digging deeper, I wonder if you might be referring to someone like Stephen King's family? His daughter-in-law, Stephanie King, has occasionally popped up in interviews or behind-the-scenes content related to adaptations of his work. She's married to Joe Hill, Stephen King's son, who's also a horror writer. While not a major public figure herself, she's tangentially connected to the industry through that legendary horror dynasty.
Alternatively, there's a chance it could be a smaller creator or indie artist—maybe a YouTube personality or podcast host? The name feels familiar in a 'tip-of-the-tongue' way, like someone who might've voiced a character in a niche anime dub or written a self-published novel. If it's the latter, I'd love to know more! The entertainment world's full of hidden gems who don't get the spotlight they deserve.
