(urth) What meaning does the family tree lend to the story itself?

[Jonathon McKitrick]

I'm still at the point of figuring out the time traveling, the multiple Sev's
and so on, but once you understand that Sev becomes the "New Sun" and saves
Urth, what additional meaning is there to be extracted by understanding his
entire family tree?  And since that really cannot be done, apparently, without
confirmation from Mr. Wolfe himself, how can the true meaning of an
inscrutable family tree ever be known?
