Are Spanish Names that end in EZ Jewish?

This question seems to be a recurring search question to this blog.  I have never met any Jew who had a name ending with EZ.  There are probably some somewhere.  After all Jews seem to be everywhere.  The attack in Mumbai, India on Nov 24, 2008 included an attack on a Chabad facility.  Which begs the question, what is the purpose of a Jewish facility in India?

In answer to the title question I have searched the internet to find an answer.  I found nothing except one person asking if there was any truth to the theory.
