   Is there a similar cat_is_ancestor_of function for pages?

   Assuming your page object is in $post (like inside a normal post loop):

   <?php
   if (in_array("95", $post->ancestors)) {
       echo "page id 95 is an ancestor of this page";
   }
   ?>

   I am looking to display a sub-navigation in the sidebar of all the child pages for a parent page. Is this the best way to achieve this?

   Could look at some examples using wp_list_pages().

   Here is my end result for those that come across this thread:

   // [not shown] special cases for post categories up here (using is_ancestor_of function)
   
   // now for the pages
   elseif(is_page()) {
   	//get post id
   	global $post;
   	$page = $post->ID;
   
   		// Some Menu for a set of pages
   		if($page == "68" || $post->post_parent == "68" ) { ?>
   			<h3>Some Title For this Set of Pages</h3>
   			<ul>
   				<?php wp_list_pages('orderby=name&child_of=68&title_li='); ?>
   			</ul>
   		<?php }
   
   		// Another Menu for another set of pages
   		if ($page == '751' || $post->post_parent == "751" ) { ?>
   			<h3>Some Other Title For this Set of Pages</h3>
   			<ul>
   				<?php wp_list_pages('depth=2&child_of=751&title_li='); ?>
   			</ul>
   		<?php }
   } else { ?>
   // standard sidebar stuff for untargeted pages or posts
