Can child page reference parent via php script?

This may be really simple or really not.

I can use <?php the_title(); ?> to reference the title of a post or page currently being called for from the DB and place it in my template.

What if I wanted a child page/post to display the title of a parent page that is maybe one or two levels above it?

Is this possible with a premade WP function or will I have to make my own?

If I have to make my own… then how?… lol >_<
