Honestly it has never occured to me to find out.
I know lots of people hold great importance to knowing what your kin name is, especially on the Draconic or Fallen side, but for me it has always been more important to know what I am.
I just know that now I am going to start thinking about it and someone is going to tell me I am called "fang tooth" or "big bite" or something equally daft. One of my guides is prone to pulling that kind of prank.
In truth it is probably linked to a name I use or something that I find particularly important in the Physical world.
For instance captive wild was written by Lois Chrysler so it might be Ysl or Fen from Wolfen, that kind of thing.
