Apparently they stemmed from this illustrators only agency http://www.thebrightagency.com/ which doesn't look too legit, seeing as the agents don't even post their last names on the site.

PM turns up nothing for either Ellie Wharton or Vicki Willden-Lebrecht.
Wharton worked in International Rights with Meadowside Books, but Willden-Lebrecht has no experience in publishing whatsoever -- at least there's none listed on their website, where you'd expect they would tout all of their credentials.
