ATWT: Carly's Past and some speculation

Last week, when Carly was having a day "nightmare" (as opposed to a daydream) about Les he said something about not being able to hide from her past.

Now, that brings up the question: What do we really know about Carly's pre-Jack past? We know she grew up in Montana. That her mother left her to marry Rosanna's rich father. And that's about it.

Now, here is some speculation on my part. We have this new Gwen character. What if she is Carly's daughter from her past (hey they did it with her cousin Molly) that she gave up for adoption long ago? If so, who would be the father?

The only bad part of this storyline is that, with Gwen as a pregnant teen, Carly would soon be a grandmother! Ack--she isn't even close to being old enough to be a grandmother.
