User blog comment:RoseCupid/Dizzie, Apping, Daringolly, or Darise?/@comment-3991308-20150809201611

I hate to be a downer, but Dolly generally refers to Holly and Darling, not Daring. It's also called Holling, but some people on Tumblr tag their ship art and fics with Dolly, and sometimes Gay Dolly to distinguish it from actual dolls.

I don't know whether there's an official shipname for Holly and Daring, but just pointing out that Dolly is generally used as another name for Holling.
