A FamilySearch Partner
Import from FamilySearch, discover new connections, and work with others — while your conclusions and your view stay yours. A standalone shared tree with a different collaboration model and different data to explore.
Start exploring freeIf you've felt others change your tree without your say, you're not alone — and you don't have to give up collaboration to keep your research.
OneGreatFamily preserves every perspective — including yours.
A different kind of shared tree
Solve the frustration of losing control when others change what you documented. OneGreatFamily is its own collaborative system — it preserves your work instead of overwriting it, and you can bring in what you've already built.
Your conclusions stay yours. Your perspective remains visible — not erased when someone else disagrees.
Multiple viewpoints sit side by side. Disagreement becomes something you can see and reason about — not a silent overwrite.
Accept or reject updates on your terms. You stay in the driver's seat.
One global tree, customized to reflect what you believe about each ancestor.
Go beyond your current tree with connections and records you won't find in one place alone.
Import your existing research — no need to re-enter years of work.

How it works
Bring in what you've already built — including from FamilySearch in a few steps.
Tap into a shared database, see matches and alternative conclusions, and choose what you believe — nothing forced on you.
Matching continues in the background while your documented conclusions stay under your control.
Advanced tools
Built-in research tools for people who live in the sources — go deeper while staying in control of what you've already proven.
Trace paths between people across the shared tree.
Visualize where ancestors lived and how families moved.
Spot patterns in your lineages with purpose-built views.
Navigate a rich, visual tree built for serious researchers.
Independent partner experiences from the same network — optional next steps when you want another lens on discovery. OneGreatFamily stands on its own; these are there when you are curious.
You don't have to choose between collaboration and keeping your research.
Collaborate with others — without losing your conclusions or your control. Keep what you've built and open new paths to explore.
