Yeah that is someone's last name.Hennessy is a real name, the cognac is just named after Richard Hennessy, who founded the brand. That's like saying that Sir Alec Guinness has a bad name.
I highly doubt the Hennesy on the resume I saw was being named after Richard himself. It also was not a last name.
This person, along with patrone, was most likely named that because their ghetto ass moms drank that liquor.
