Child pages with same names under different parent pages

I’m trying to create two child pages with the same names under parent pages:

• parent1/contact-us/
• parent2/contact-us/

Each of the parent pages will be a different theme, so the child pages aren’t identical. But WP is appending a “-2” to the page name on the 2nd “contact-us” page (“contact-us-2”).

Is there any way I can have the two pages with the same root of “contact-us” or will I just have to rename the 2nd page to something different?

The reason I ask is that this site is a transfer from Drupal and I want to keep the page links the same. If I can’t, then I ‘ll deal with it.

Thanks!
