Some thoughts on the structure: I think it is quite well done and inviting. Some further suggestions:
# In the kids' section, one link will be enough. I find the repetition of the link in the text disturbing the layout, especially if it is diretly below the other like with Nico
# Links to the actors page might be supplied in this section (for example by an indicateion "portrayed by xyz" in small letters
# The parent's names should be indicated full (as the kids') so that everyone immediately can see who is the parent of whom.
# Some discuission points herr are like polls. One or two polls may also be added on teh main page using the poll tag.
# This wiki also is about the comics. On the main page, however, the comics are only mentiond in a small paragraph under "Help us grow"
