Matrilineality is the tracing of descent
through the female line corresponding
to a societal system in which each person
is identified with their matriline;
             – their mother's image –
and which can involve the inheritance
of property and/or titles. A matriline is
                                     a line of descent from
a common female ancestor
to a descendant of either ***
in which the individuals in all intervening
                          generations are mothers –
in other words, a "mother line".
In matrilineal descent,                          
individuals belong to the same
group as their mother.                            
                         The matriline of historical nobility
was also called the enatic or     Uterine ancestry;
