There is far more going on than the names of the women. Beautiful women don't necessarily become mothers of mighty men.
Like Feudal Lords? Sure they do.
Their looks are emphasized by their names.
The lust for their looks and sexual sin is emphasized by marrying two instead of one.
The violence of murder is spreading emphasized by the killing of the young man.
The lack of repentance and self justification is emphasized by the song or boast of Lamech that he would get away with it if Cain did, because he was defending himself and so
we see a hardening of the heart emphasized.
All of this highlights the working of sin in the souls of men and the path of degradation that is still evident today in the life of each individual before conversion.
The Fuedal Lord, The Strongest rules over the weak, Mighty men of renown is a result of the process of yielding to the sin that crouches at the door that would master them.
