The free FamilySearch website is home to the world’s largest online family tree. Known as the FamilySearch Family Tree, this shared family tree is home to information about more than 1.2 billion ancestors, which has been contributed by millions of descendants.

What’s a “Shared Family Tree”?

FamilySearch’s unified family tree differs from the tree-building experience at most other websites. Instead of concentrating efforts on privately constructing their own individual trees, FamilySearch tree builders cooperate to build a single, shared tree that helps you and others discover more about ancestors and other family members.

One Profile for Every Deceased Person

The FamilySearch shared tree strives to have just one public profile for every deceased person who has ever lived. Descendants contribute what they know about a person to a single, shared profile, rather than scattering their knowledge across multiple profiles on several trees, some of which may have privacy barriers.

Note: On the FamilySearch Family Tree, personal account information and any details about living persons are kept private. Only deceased persons have public profiles.

Why Use the FamilySearch Shared Tree?

The FamilySearch Family Tree can help you more easily connect to your family and build your family history. Here are five ways it might help you.

  1. Discover New Information
    A shared family tree can help you discover new information about your ancestors and even find relatives you weren’t aware of. Each piece of information someone adds—a document, a photo, a memory, a burial location—may shed light on an ancestor’s identity or life experiences.
  2. Build Your Tree with Ease
    It can be tedious work to fill out each ancestor’s profile for your family tree on your own. When you connect to the FamilySearch shared tree, some of your ancestors may have an abundance of information already in their profile. Even if you are the first to add a specific ancestor to the shared tree, FamilySearch can show you possible records for that ancestor, and other family members can help you by filling in what they know.
  3. Get a More Complete Picture
    The overall result of a well-sourced shared tree can be much more complete and accurate than individual trees. Although information entered by users may at times differ from what you know about your ancestor, the FamilySearch Family Tree enables all descendants to share information that others might not know and add sources to confirm correct information.
  4. Connect with Other Descendants
    Working together on a global tree also helps descendants connect with each other. You may find a relative who has visited the same graves, asked the same questions about—and even learned to love or admire—the same ancestors.
  5. Work on Your Family History for Free
    When you sign in on a free FamilySearch account and connect yourself to the shared family tree, you’ll be able to see all your connected ancestors in a personal tree view. This online family tree lets you add life events to your ancestors’ profiles; look at a map of where they may have travelled; view and add photos, memories, and records; and much more.

    1. Guten Tag Rafael, ich bin Sr. Bensch. Sie fangen damit an, dass sie auf ein Blatt Papier alles aufschrieben, was sie über Ihre Familie wissen oder von anderen aus Ihrer Familie erfahren.

  5. Estou amando fazer minha árvore aqui na Family Search.
    Meu avô não se lembra de muita coisa da família dele, porque perdeu os pais quando criança, mas através de poucas lembranças eu consegui redescobrir o seu passado! Ele ficou tão emocionado por saber a causa do falecimento dos pais, quais eram os nomes de seus avós, por ver a certidão de nascimento de todos os seus irmãos…
    Estou sem palavras para descrever o quanto fazer a árvore da minha família tem sido gratificante para todo mundo da minha família!

    My grandfather doesn’t remember much about his family, because he lost his parents as a child, but through few memories I was able to rediscover his past!

    I am at a loss for words to describe how rewarding my family tree has been for everyone in my family!
