Deletion of Arquette family

Comment: If we're going to do family articles, then how one differentiate between duplication of aterial in articles, navigation between articles, and #DIR (specifically guideline 1 re: geneaology)?  ?  For example, there is a whole Barrymore family tree in the above-mentioned article, not all of whom are famous or even have articles themselves.  The article even states that only four of the younger Barrymores went into acting, and those four are the ''only'' ones who have WP articles.  So I guess I'm a bit confused, because that "family article" looks a lot like a genealogical directory to me
