Gremoire for House Sigil !?

Hi, everybody!

I would like to ask a question about the House Sigils. As you might know EA had mentioned about them in his book Evoking Eternity, e.g. House of Kel Sigil. I would like to know about Gremoires that have such House Sigils in them. Most of my search results are till now zero. I would like to know whether anybody could give some better references or ideas in this regard !?

Thank You
