ic might marry even without the
intervention of his father, according to the mode prescribed by our
constitution.

1 It is not every woman that can be taken to wife: for marriage with
certain classes of persons is forbidden. Thus, persons related as
ascendant and descendant are incapable of lawfully intermarrying; for
instance, father and daughter, grandfather and granddaughter, mother and
son, grandmother and grandson, and so on ad infinitum; and the union of
such persons is called criminal and incestuous. And so absolute is
the rule, that persons related as ascendant and descendant merely by
adoption are so utterly prohibited from intermarriage that dissolution
of the adoption does not dissolve the prohibition: so that an
adoptive daughter or granddaughter cannot be taken to wife even after
emancipation.

2 Collateral relations also are subject to similar prohibitions, but
not so stringent. Brother and sister indeed are prohibited from
intermarriage, whether they are both of the same father and mother, or
have only one parent in common: but though an adoptive sister cannot,
during the subsistence of the adoption, become a man's wife, yet if the
adoption is dissolved by her emancipation, or if the man is emancipated,
there is no impediment to their intermarriage. Consequently, if a man
wished to adopt his son-in-law, he ought first to emancipate his
daughter: and if he wished to adopt his daughter-in-law, he ought first to
emancipate his son.

3 A man may not marry his brother's or his sister's daughter, or even
his or her granddaughter, though she is in the fourth degree; for when
we may not marry a person's daughter, we may not marry the granddaughter
either. But there seems to be no obstacle to a man's marrying the
daughter of a woman whom his father has adopted, for she is no relation
of his by either natural or civil law.

4 The children of two brothers or sisters, or of a brother and sister,
may lawfully intermarry.

5 Again, a man may not marry his father's sister, even though the tie
be merely adoptive, or his mother's sister: for they are considered to
stand in the relation of ascendants. For the same reason too a man may
not marry his great-aunt either paternal or maternal.

6 Certain marriages again are prohibited on the ground of affinity, or
the tie between a man or his wife and the kin of the other respectively.
For instance, a man may not marry his wife's daughter or his son's wife,
for both are
