How do I build a Ou family tree?
Start with your own branch: record the ancestors you are sure of, then parents, siblings and descendants, generation by generation, with dates, spouses, migrations and burial places. Then invite relatives to fill in their own branches.
The KinTraces genealogy workbench lets a family build a Ou genealogy together online — relatives claim their own entries, adoptions and dual heirship are recorded on both sides, every change is logged, and the tree can be printed as a traditional Chinese genealogy (vertical register, Su or Ou style, pagoda chart) or a Western Register / Pedigree, or exported as GEDCOM.
What are Ou generation names (zibei)?
Many Chinese lineages share a generation poem: each generation takes one character from it in their given names, so cousins of the same generation share a character. Different Ou branches use different poems — there can be dozens for one surname — so a poem from another branch cannot simply be borrowed.
The most reliable source is your branch's own genealogy; otherwise, collect names from elders, gravestones and ancestral halls, look for the shared character in each generation, and compare with genealogies from the same ancestral place.
