## Does 866 cM shared suggest half aunt rather than aunt?

1

There is a joke in my family that my father's father is not his biological father. He only has sisters and his father is dead, so there's no possibility of a true test. But I'm his daughter and I did a DNA test, and here's what I got.

I got DNA results back and here's what it says about one of my aunts that tested too. Great aunt or cousin is the link they gave us.

Does that actually mean the joke is true and my aunt is my half aunt?
