Theme 2016: Customize About Us, Locations and Contact Us pages

Hello,
I am a newbie. I have created a child theme from 2016. I am trying to use WordPress as a shell for my site. I am not creating a blog site and am not going to use any blogging on my site. I have therefore created template pages and custom headers/menus for my site pages.
But, I cannot figure out where to find the files for the about, location and contact us pages. I want to modify those pages the same way I have modified the index.php file. I like the functionality of those pages, I just want to have those pages use my headers and menus.

I see that many responders like to see the site, so it is veebstudentservices.org.

Not much to look at yet, but hopefully with your help I will get over this hump.

Let me explain a little further.

When I wanted to edit the home page, I was able to find the php code in the index.php file in the parent template and create the page-index.php file using the code from that file from the parent template. I then modified the code from that file and used that file as the template for the home page.

I want to do the same for the other pages, like about, location and contact us, but I cannot find the files with the php code for those pages. I want to create new page-abput.php, page-location.php and page-contactus.php files and use them as templates for the pages within wordpress. What I am looking for is the original php code for those pages so I can edit/mofdify it to suit my needs.

I read the documentation for creating the page templates. But, unfortunately, it does not tell me how to modify the existing code that builds these pages. I have ben told that these are just pages built by WordPress. I am looking for how those pages are created by WordPress, so that I can modify them.

In other words, if WordPress is building those pages, then what process occurs when I click the Location link? There must be functions that are called and code that is run that creates those pages dynamically.

I like the pages. I do not want to completely recreate the wheel. I just want to change them to use a different menu and to not display the site image.

It looks like they all use the get_header, what I need to know is what process occurs that writes the rest of the page? Is that a proprietary WordPress process that cannot be modified?
To write the rest of the page, it’s processed in your theme usually via the theme’s page template, or a modified post template.

After posting to the How-To forum, I was told “You’ll have to investigate your theme, or check with your theme’s support, for specifics.”

So, here I am. =)
