They have already confirmed that Aquilus, Altaïr, Ezio and Connor have no blood relation to each other. And this has been mentioned numerous times. Please stop bringing it up, people, and take a look around yourselves.

Connor is half Native American, half British. With repelling all outsiders he means repelling all the Europeans who invaded his ancestors' land. By being the outsider he means that he doesn't belong to the Caucasian colonists because of him belonging to the Mohawk tribe.
