Get Parent Category?

Is there a way to make a header tag display a category and subcategory together, instead of just a single category?

h2><?php _e(‘Vacation Rental Listings in’,’cp’)?> <?php single_cat_title(); ?>, NC (<?php echo $wp_query->found_posts ?>)</h2>

The above displays as “Vacation Rental Listings in (Subcategory), NC”

I need it to display as “Vacation Rental Listings in (Parent Category), NC”

Any direction you can provide would be greatly appreciated! =)
