Forum:Ravenclaw Crest Similarities

I noticed that the Ravenclaw crest used in the movie and fan products is similar to the real-life crest of the MacDonnells of Glengarry, known as “the Rock of the Raven”. Interestingly, the clan’s historical seat, Inverness, is actually close-by to where it’s said that Hogwarts is on its page.

What are your thoughts about this?
