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.
