Q suggests Merkel is related to Hitler? From what I can tell he wants us to focus on Merkel's father. Horst was a pastor in East Germany but he had been tapped by the communists. Q team probably has dirt on both her and her father.

It says Angela's granddaughter, bearer of the same name, is still alive and took care of the grave of Adolf Hitler’s parents, but the grave stone is meanwhile removed.
Perhaps that's the woman we're supposed to dig up info on.
