Q04: What would a "M*A*S*H Family Tree" look like?

A04: Here is a somewhat incomplete list of M*A*S*H family members:
    
    Note:  - A question mark (such as "(sister?)") means that the relative
    -----    has been mentioned on the show, but I do not yet know his or
	     her name.
	    - A blank line means that no mention (as far as I know) has been
	     made of this type of relative... parents excluded, of course.
