'Families' in the Bible

In Jerusalem also Jehoshaphat appointed some of the Levites, priests, and heads of the fathers’ households of Israel to render the judgment of the Lord and to judge disputes among the inhabitants of Jerusalem.

And stand in the holy place [of the priests] according to the sections of the fathers’ households of your fellow kinsmen the lay people, and according to the Levites, by division of [the families of] a father’s household.

Then they removed the burnt offerings, to distribute them to the sections of the fathers’ households of the lay people to offer to the Lord, as it is written in the Book of Moses. They did the same with the bulls.
