How the WikiTree Community Collaborates on One Global Family Tree

Updated

WikiTree is built around a single shared tree rather than thousands of separate personal trees. Members — from advanced genealogists to casual family historians — contribute profiles to that one tree, sign an Honor Code, and use community tools like the G2G forum, Connection Checkers, and the Question of the Week to help each other research and verify connections. The site describes itself as a collaboration "for our cousins and descendants to enjoy for free, forever."

One tree, many contributors

The defining feature is that everyone works on the same tree. WikiTree reports 1,420,721 community members and 46,511,696 ancestors and cousins on the tree, with 16,861,115 of those having DNA connections. Because profiles are shared rather than siloed, collaboration happens directly on the profile: members edit, merge, source, and discuss the same person.

This is different from sites where each user keeps a private tree and collaboration means comparing GEDCOMs. Here, the unit of work is the shared profile.

The Honor Code as the collaboration contract

Members who sign the Honor Code are described as gaining member benefits and seeing fewer ads. The Honor Code functions as the behavioral agreement that makes open editing workable: it sets expectations for accuracy, sourcing, and how members treat each other.

In practice, signing it is the step that turns a visitor into a collaborating member. The site frames the community as friendly and mutual-aid oriented: "We're a friendly community and we help each other."

Community features that organize the work

Feature What it does How members use it
G2G forum Discussion and Q&A space Ask questions, request help, flag issues
Connection Checkers Weekly game around notable people See how you relate to 12 notable explorers, then verify the connection with reliable genealogical sources
Question of the Week Recurring prompt Share DNA ethnicity estimates, one-name studies, and other themes
Profile Examples Sample profiles of well-known figures See the expected standard for a finished profile
Member Interviews Member stories Understand what long-term contributors value

The Connection Checkers game shows the collaboration pattern clearly: the task is not just to find a connection but to "attempt to verify your connection with reliable genealogical sources" — and to "ask when you need help."

How a contribution actually flows

  1. Search or start a profile. Use person search or advanced person search to find whether the person already exists on the tree.
  2. Check before creating. Because it is one tree, the goal is to improve an existing profile rather than duplicate it.
  3. Add sources. Verification with reliable genealogical sources is the stated standard, not just adding names and dates.
  4. Ask for help when stuck. The G2G forum and the weekly prompts are the designated places to raise questions.
  5. Sign the Honor Code if you want member benefits and to participate as a member rather than a reader.

The expected result of each step is a better-sourced shared profile, not a private copy.

What members say collaboration gives them

Member interviews on the site describe the value in terms of permanence and family connection. Skye Sonczalla (member since 2016) says she feels all the information she has collected in 25 years of research is safeguarded. Roger Peterman (member since 2025) says he values his WikiTree efforts more highly than any prior accomplishment because "we actually can leave something real and permanent behind." Kahlil Thomas (member since 2019) cites how close WikiTree has brought him to his extended living family.

These are member statements, not guarantees, but they point to why people accept the shared-tree model: contributions persist and are visible to relatives.

Where collaboration can get difficult

  • Disagreement over a profile. Because editing is open, two members can hold different views on the same person. The Honor Code and the G2G forum are the mechanisms the site provides for working that out.
  • Verification is work. The Connection Checkers instructions explicitly pair finding a connection with verifying it against reliable sources — the connection alone is not the endpoint.
  • Scale cuts both ways. With tens of millions of profiles, searching before creating is essential to avoid duplicates.

If your goal is a private, fully controlled tree, this model will not fit. If your goal is contributing to a shared, sourced tree and getting help from other researchers, the Honor Code plus G2G plus the weekly features are the working parts to start with.
