- Brother Crowley may be named after the famous 20th-Century occultist Aleister Crowley. Brother Crowley sends you to Brother Anton: Anton LaVey was the American founder of the Church of Satan, and was influenced by Aleister Crowley.
- Though clearly unlikely to be a relative, Darius Crowley also shares his surname, perhaps pointing a Gilnean connection in his lineage, although this is purely theoretical. Darius Crowley was also introduced to the Warcraft storyline only recently in World of Warcraft: Cataclysm, making a relative connection even less likely.
