I have. 

On a side note, I might have another that's interested in this thing. My roomie/sig-o. AS for a hougan, I was thinking about that myself. Lot of thaumaturgy there. 

The character I was considering is one Brandon Greene, a 'paranormal investigator' formerly employed by Allied Paranormal/Private Investigative Services (APIS), as a general investigator and 'occult expert'. Somebody that can handle things that bump back a little harder, and handle specialty situations. - He was involved in a relationship with the team leader for some time, romantically, a one Sakura Moyotada, but  they split up a few years ago. After that, he packed up his book/new age store in Amarillo Texas and moved on. - I can easily see him moving ot New Orleans, especially to study Voodoo/hoodoo both academically and for magical pursuits, as well as keep an eye on them for the White council. 

In his history I do have ties to Elaine Mallory, and possibly Warden Ramirez, but those aren't intended to do anything more than give him some flavor, and possibly give him access to a little backup from time to time. - He might have been deputized as a Warden as he does have combat experience, if this takes place during or post the Vampire war.
