Single mothers

I've encouraged my students to google a phrase to get texts on a more specific topic.  Demonstrating it with "single mother", some of the first-page hits I got were: this Guardian piece on J K Rowling and her rags-to-riches story (from July 1997); this Independent comment by Kate Saunders on her own experience (from Apr 2007) and this wonderful example from the Daily Mail about a single Nigerian mother who lives in a big house that - guess what - we the taxpayers are funding (from Nov 2008).  There's clearly enough here for an investigation, but any of the texts could also be used as part of an 'institution' investigation into the idea of Family, or further texts about J K Rowling or Omowunmi Odia could be found for a piece on individuals.
