Female biographies are especially susceptible to violating WP:LASTNAME, i.e. the subject of the article being referred to by their first name rather than by their surname (last name). A program has been written to go through and attempt to identify articles that may suffer from this problem. The first results of this program are below (culled from a single category). If you want to help, choose an article to review and either remove it from the list or strikethru it once you have finished.
Note: It is sometimes appropriate to refer to someone by their first name within an article. Please read WP:LASTNAME before correcting any of the articles.
