Free shared family tree with source-backed profiles and DNA links.

WikiTree is a collaborative genealogy site where members build one shared family tree rather than separate private trees. Profiles are intended to be supported by reliable sources, with community discussion, relationship tools, and DNA-linked connections helping users verify and extend family lines.

Why it stands out

  • Built around one collaborative tree, reducing duplicate isolated family trees.
  • Strong emphasis on sourced profiles rather than unsourced name collection.
  • Large long-running community with millions of profiles and DNA-linked connections.
  • Free access model, with costs supported by unobtrusive advertising.
  • Community workflows encourage members to ask for help and improve each other’s research.

Good to know

  • Because it is a shared public tree, edits and conclusions may require collaboration rather than full individual control.
  • Profile quality depends on the sources and care contributed by community members.
  • The site describes DNA connections, but it is not presented as a DNA testing service itself.
  • Non-Honor-Code visitors may see advertising, since ads help fund the free service.

Under the radar: Try the rotating Connection Checker challenge even if you are not focused on notable people; it can reveal unexpected branches where your sourced research may connect into the larger tree.
