The late Freddy Mercury, of Queen, was descended from a line of followers of what religion? Where did these people come from? Where did they originate?

Okay, I might have gotten on the wrong track but here goes:

Freddy Mercury--> parents-->Zoroastrians-->Persia-->Mesopotamia

Kelleygirl--->Almost Exactly Right !

Freddie---> Mom & Dad Mercury---> Zoroastrians ---> India --->Persia (Although in his parents' case, they came to England from Zanzibar.)
Zoroaster is the same name as Zarathustra. (Who Thus Spake once)

Zoroastrians who came from India are also known as Parsis or Parsees.

Freddy's birth name, - Farrokh Bulsara

Okay, Dorian, I see what you have,AND I'm sure that you're correct, but here's why I came up with my "gems":

This site says that his parents were Persians--
http://www.musiceffect.com/CEMETERY/freddy_mercury.html

And then I went to a site called The Persians and that's where the Zoroastian religion had its roots--

The site wasn't wrong, and neither were you. My information is simply a little more detailed. Thanks for the answers.
