According to this, Eticho I von Ammergau, Graf im Ammergau, is my 36th ggf, but his father, is listed as my 34th great uncle.
Conrad II, "The Younger", is my 34th ggf, who is the brother of Eticho's father.
Another brother of Welf II, is Robert I, King of France. He is my 33rd ggf.
I'm obviously missing something in regards to how my 34th uncle ended up as my 36th ggf's father. (?) Is that an inaccuracy, the result of an incestuous relationship, or is it just a matter of the shortest path to me through this line, being that he is my uncle, rather than my great grandfather. (which, may still be the case. (?) )
