Names

Names are interesting things in Stardust.  I noticed two primary things about them.  First, the names of people in the village are quite ordinary.  We see names that are still commonplace, such as Victoria, Thomas, Louisa, and others.  However, on the other side of the wall, names are very different.  The seven princes might have just as well been named One, Two, Three, Four, Five, Six, and Seven.  Their sister's name was Una.  Una is not a traditional name.  It even alarms the spell check as I type this page.  For this reason, as soon as the story begins, we know there is something peculiar about Dunstan.  His name is different.  Even though he is not the star of the show, he is the beginning.  And when his son appears, we know right away just where the child came from - we would have suspected even if the back story had not been told. 
Second, great detail is given to names, and yet not, too.  The little hairy man remained nameless, even after he became Tristran's traveling companion.  He had somewhat of a significant role in the story.  Yet, seemingly insignificant people, such as Tilly the pot-girl and Lacey the ostler, are given names and their names are made clear to the reader.
Often in fantasy, names are given power.  For example, in Harry Potter, mentioning the name of Voldemort would cause others to jump in fear, and later would draw him right to you.  While Stardust does not follow directly in this fashion, I think it may be a similar idea.  While I am not entirely sure what they may signify in this book, names are significant.
