WOW, that is the rub.
Starting early is the key.
But I still did not answer the question.
The idea of having a total listing of all Brothers of the Zeta is the key!
Starting from scratch is going to be tough with out the key. # 1 being the first of course.
The Tree is nothing more than a seed = #1. Then it grows with branches and names.
The only problem I have seen is the Limbs overwhelming the Zeta.
It has to be kept in prospective.
