Wikipedia:Articles for deletion/List of families
List are as valid as categories per .  Families are commonly used as a way for structuring taxonomic lists.  For examples, see ''http://books.google.co.uk/books?id=XIL9adYYeSIC IUCN red list of threatened plants'' and ''http://books.google.co.uk/books?id=9tiDHrzxf9QC Check list of the freshwater fishes''.  We have numerous :Category:Taxonomic_lists|taxonomic lists and there seems to be no good reason to discriminate against families when reliable sources such as these do not do so
