Update for those on email ... I corrected the line ...
"For instance, in a "term chart", say you SEE ONLY that the parents of Ego are "F & M" (father and mother); then you might IMPLY their parents are "MF, MM, FF & FM" (i.e. mother's father etc) when not shown. But where do you stop?" to what I meant ... "For instance, in a "term chart", say you SEE ONLY that the parents of Ego are "F & M" (father and mother); then you might IMPLY their *parents' parents* are "MF, MM, FF & FM" (i.e. mother's father etc) when not shown. But where do you stop?"
