Where is the civicrm database?
You can find the civicrm database listed in the civicrm.settings.php

 &lt;wordpress&gt;/wp-content/uploads/civicrm/civicrm.settings.php


Apart from that , you have two possibilities

1)Wordpress and Civicrm both use same database

2) Civicrm has    separate database

If wordpress and civicrm has same database , you can search in wordpress database tables which have prefix civicrm_*
