How to update heading tags with custom font in virtue theme

I have used the free virtue theme and I like it.

I have added a child theme and loaded 2 x custom fonts. However, I cannot get the h1, h2 etc tags to pick up either of the custom fonts. They still display with the default settings in the virtue theme. The paragraph <p> tag does recognise the custom fonts.

Here is my child theme css.
