Conditional Logo Image for URL Containing Parent Page

Hello,
I am trying to setup conditional rules for the logo based on what the URL of the page contains. My aim is the home page (/) will have the default logo, and all pages under one parent will a different logo, and another parent pages will have another different logo.

So:
/home/ = Default logo in Enfold settings
/parent1/ = Custom Logo 1
/parent1/page1/ = Custom Logo 1
/parent2/ = Custom Logo 2
/parent2/page2/ = Custom Logo 2
and so on…

I’m currently using

add_filter('avf_logo','av_change_logo');
function av_change_logo($logo)
{
    if(is_page( array( 13, 17, 20, 23, 26, 28 ) ) )
    {
    $logo = "URL of Custom Logo 1";
    }
	
    f(is_page( array( 14, 15, 21 ) ) )
    {
    $logo = "URL of Custom Logo 2";
    }
    return $logo;
}

Is there anyway to make it so that I don’t have to put in a page ID everytime I create a new page under the parent page? Thank you!
