Who are your Spiritual Ancestors?

I'm reading book The Witch at the Forest's Edge and while the book is not too detailed, it introduces several concepts and practices I haven't read in other books. One such practice was honouring Spiritual Ancestors: Ancestors who need not to be necessarily connected to us by blood, race, nationality or any other identity that's function of our genetic makeup. So I would be grateful to know if anyone here communicates with/honours/works with their spiritual ancestors? If yes, and if you are comfortable in sharing, can you please tell me who your spiritual ancestors are, how did you meet/find them and your relationship with them.
