I’ll be honest, I don’t know too much about Lilith besides her being part of Jewish mysticism, I believe 
(I could be off base there, I’m not sure). I know that we’ve got a lesson here on Spells8 about her though if you haven’t seen it already 
Lilith’s origins and essence are uncertain . She is considered a primordial being, a demon, a vampire, a Goddess and a sorceress, depending on the path you choose to follow. Her appearance is that of a very beautiful woman, with long red hair, and sometimes winged.
We also have many other posts here on the forum from other members about Lilith. I recommend checking those out as well – more information is probably shared there

Though I don’t work with her myself, I wish you the best of luck!
