Whoever was begotten in an illegal marriage, or out of marriage, was excluded from the membership of the community.

On this account the Roman burgesses assumed the name of the "father's children" (-patricii-), inasmuch as they alone in the eye of the law had a father.

The clans with all the families that they contained were incorporated with the state just as they stood.

The spheres of the household and the clan continued to subsist within the state; but the position which a man held in these did not affect his relations towards the state.

The son was subject to the father within the household, but in political duties and rights he stood on a footing of equality.
