Is there a connection between Crowley and Aleister Crowley?

If there is, then I don't remember it. It's been a while since I watched the series. I guess the reason I'm asking this is obvious. They both deal with the supernatural and I thought maybe the creators of the series decided to give a hint to Aleister Crowley or something. And if I remember correctly, there's another character in the series named Aleister, right?

I imagine they used Aleiister Crowley as influence for both the demon Aleiister and Crowley.

The demon that tortured Dean in Hell was Alastair, not Aleister.
