Actually when I was thinking of their names I was naming them after Sherri and Terri, the twin girls from The Simpsons. Aside from Mary I couldn't think of anothet girls name that rhymes with Sherri or Terri, so I just used Sherry just ending with a different lettet. Thanks for pointing that out. I never that could also be a nod to Mary Shelly.
