First of all Thanks for contributing! We really do need more editors adding content. I can't say that strongly enough!
Having said that, I think we need to establish clearer guidelines for what should go in the "Family" section of the infobox. You have spent some time researching families of the characters in the episode The Village That Rose from the Dead and updating the infobox.
The Layout guide says to limit the entries to immediate family, which in my view, means Parents, Siblings and Children. I think that it would add interest to the article to add anyone else in the body of the article - see for instance Finn Thornberry - fiancee, unnamed child, cousins, etc. should be left out and put in the body of the article for interest.
I hope this clarifies and doesnt' put you off of wanting to continue to contribute.
p.s. - Until one of us has the time to add info to the body of these articles, we should leave your edits as-is. They add a little interest even in the infobox, but I would prefer them to be in the body. Steve (talk)
