Ancestor is a generic term. For some types of relationships, a more specific term can be used. Since the relator between things in the example hierarchy is "obeys" (ie fido obeys luke, luke obeys trinity, trinity obeys god) the ancestor could be described more specifically as commander. If one runs the report, it actually says "common ancestor", since XDb1 has not been programmed to accept or use a more specific term for ancestor in a specific hierarchy.
