 . *** Kinship terminology.
 .
 .  Great-grandparents: The grandparents of your parents; the parents of
 .   your grandparents.
 .
 .  Grandparents: The parents of your parents.
 .
 .  Grand-aunts/grand-uncles: The brothers and sisters of your
 .   grandparents; the aunts and uncles of your parents.
 .
 .  Aunts/uncles: The brothers and sisters of your parents.
 .
 .  Nieces/nephews: The children of your brothers and sisters.
 .
 .  Grandnieces/grandnephews: The grandchildren of your brothers and
 .   sisters; the children of your nieces and nephews.
 .
 .  First cousin:  First cousins share a pair of grandparents.  The
 .   children of brothers and sisters are first cousins.  The child of
 .   your aunt or uncle is your first cousin.  The child of your first
 .   cousin is your first cousin 'once removed'.  The child of your
 .   grand-aunt or grand-uncle is also your first cousin 'once removed'.
 .
 .  Second cousin:  Second cousins share a pair of great-grandparents.
 .   The children of first cousins are second cousins.  The children of
 .   your parents' first cousins are your second cousins.  Your children
 .   and the children of your first cousins are second cousins.
 .
 .  Third cousin:  Third cousins share two great-great-grandparents.
 .   The children of second cousins are third cousins.  The children of
 .   your parents' second cousins are your third cousins.  Your
 .   grandchildren and the grandchildren of your first cousins are third
 .   cousins.
 .
 .  Fourth cousin:  Fourth cousins share a pair great-great-great-
 .   grandparents.  The children of third cousins are fourth cousins.
 .   Your grandchildren and the grandchildren of your second cousins are
 .   fourth cousins.
 .
 .  'Step' brother/sister/father/mother/son/daughter:  Related by
 .   marriage , but not by birth.  When a person with children remarries
 .   the 'step' relationships become involved.
 .
 .  'Half' brother/sister:  Related by birth through one parent only.
 .   When a person with children remarries and has more children, the
 .   'half' relationships become involved.
 .
 .  'Removed' cousins:  Cousins who are descended by differing numbers
 .   of generations from a common ancestor are cousins 'removed'.  For
 .   example, the children of first cousins are second cousins, but a
 .   person is a first cousin 'once removed' from the child of his
 .   first cousin.  A first cousin 'once removed' is sometimes referred
 .   to as a second cousin.
 .
 .   'Half' cousins:  Cousins who share a single ancestor, rather than a
 .   pair.  This is a result of ancestors being half-siblings due to a
 .   remarriage.  A 'half' first cousin is sometimes called a second
 .   cousin; a 'half' second cousin is sometimes called a third cousin.
