Ah western
ancestral spirits bragging rights or your pedigree.
Hm... if I wasn't suffering a migraine & need to be up early to greet someone off a plane I'd explain it properly. I have, after all, known what ancestral spirits were since I was but a child.
However, I suggest just to read this.

It is a basic summary but gives a general understanding. It varies between societies, however, the general concept of ancestral spirits is the same.
To the OP feel free, if you still linger on the forums, to PM me.
