Loading and unloading Google fonts

How do I first unload the Google fonts that get loaded with roots and then load my own choices? Is there a handle that I can use with wp_dequeue_style?

Roots does not come with Google fonts, where are you seeing this?

Maybe this is related to Shoestrap? https://github.com/shoestrap/shoestrap-3

Now I realize that the Google fonts are being loaded by the admin of WordPress. The link is not there when I am logged out.
