There's always been some mythology about how Marland had X, Y and Z 'in his bible' years after his death - I always wondered about the claims re: Carly and others on ATWT. I can believe he created them, but there's a lot of people who also claim ownership of the Carly on GH. For example Claire Labine, I believe, explicitly said she created Carly Roberts/Benson, but I'm not so sure how much the Guza team after her would agree with details of that. I often wonder if Marland or Labine creating certain later characters on their respective shows goes to the original vague concepts and not much else.
