Hi Jim,
The Site Title is in the header.php file.
About half way down the file you will see something like:
<div class="site-branding">
<?php endif; ?>
<strong><h1 class="site-title"><a>" rel="home"><?php bloginfo( 'name' ); ?></a></h1></strong>
<p class="site-description"><?php bloginfo( 'description' ); ?></p>
</div><!-- .site-branding -->
[Moderator Note: Please post code & markup between backticks or use the code button. Your posted code may now have been damaged by the forum’s parser.]
Specifically:
<?php bloginfo( ‘name’ ); ?> is the site title.
<?php echo esc_url( home_url( ‘/’ ) ); ?> is the link to the home page of the site.
