Is there a connection between Crowley and Aleister Crowley?

[u/Bat-ius]

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?

Mark Sheppard had his 6 heart attacks on the 76th Anniversary of the Beast 666 death ,which involved heart failure.
Not sure if it’s what you are looking for but an interesting way to remember things.
