A family number, and a head of the family
Module
Families
The family as the unit you actually deal with — one number, one head, everyone in it, and the phone that reaches them.
What it does
Families, in practice.
Every member linked once, and seen from each record
The family phone, when a member has none of their own
A directory that reads by family, not only by person
Runs well with

Put Families to work.
Thirty minutes, your own data, an honest answer.
