Wendy Darling had two younger brothers, John and Michael. Their parents' names were George and Mary Darling. It might be fun to start a Darling family in VF and see if they can have the right kids - although they'd have to be in girl, boy, boy order. There's a dress that lloks a little like Wendy's in VF - the one with the white apron. John has glasses and wears a top hat so he might be a little more difficult to dress.

I don't know how you could account for Peter Pan; he wasn't related to Wendy's family.
