Answer:
I found this (I hope it helps):
Roman citizens are bound together in lawful matrimony when they are
united according to law, the males having attained the age of puberty,
and the females a marriageable age, whether they are fathers or sons
of a family; but, of the latter, they must first obtain the consent of
their parents, in whose power they are. For both natural reason and
the law require this consent; so much so, indeed, that it ought to
precede the marriage.It is not every women that can be taken as a
wife: for marriage with certain classes or persons is forbidden.
