We are only traversing the children of women who matrilineally
descended from Mary Smith. Susan is a child of Jennifer who is
married to Michael Johnson, Mary's Grandson, so Susan is not a
matrilineal descendant of Mary. You can change the traversal
rules. For that you have to modify Men::accept() and Woman::accept()
but it is not required in the lab.

Thank you,
