“We have had fabulous experiences with OneGreatFamily.com. We went from a few hundred people in our PAF program to over 10,000 each in OneGreatFamily.com.”
How we're different
Built for one connected tree—not a pile of separate files
Six ways we focus on automation, collaboration, and clarity. Plus how our model compares to typical online tree collections.
Six differences that change how fast you make progress
Same ideas members have relied on for years—stated plainly for researchers deciding where to invest their time.
Automatic merging
When the same person appears in two contributors' trees, OneGreatFamily merges them into one connected profile—so you spend less time exporting, importing, and reconciling by hand.
Duplicate cleanup, built in
Our systems work to identify and collapse redundant entries across the shared tree, so you are not fighting the same ancestors in multiple places.
Always-on matching
The service continually compares people you add against the wider tree—working around the clock to surface possible matches and new connections for you to review.
Genealogy Handprint™
Our patent-pending approach captures how your family lines connect into the larger tree—not just isolated names—so context stays visible as you research.
One tree, your view
Everyone contributes to a single collaborative structure while keeping a perspective on how their own lines tie in—shared progress without giving up your lens on the data.
Conflicts you can resolve
Where researchers disagree, differences are surfaced clearly so you can zoom in, compare sources, and decide what belongs in your line—instead of silent guesswork.
Three kinds of “online trees”—only one works like this
Most sites are a collection of separate trees, or linked profiles you stitch together yourself. OneGreatFamily is designed as a single, collaborative structure—with 287,748,149 pedigree-linked names and counting.
A collection of separate trees
Typical pattern: many independent uploads side by side.
Each tree lives on its own. You search manually, and when you find a match you often download, merge offline, or re-key data yourself.
Trade-off: You carry most of the integration work.
Linked trees
Profiles linked across sites or databases.
Trees stay distinct, with bridges between people who might be the same. You still review and accept links—even when a match is obvious.
Trade-off: More clicking and confirmation; links may sit behind extra paywalls.
Our model
One collaborative online tree
OneGreatFamily
One shared tree with automatic deduplication and merging, continuous matching, and full chaining—so tying into the core often brings in large branches automatically.
Trade-off: Only one global tree of this design—built for speed and collaboration instead of isolated files.
What members say
Outcomes from real research—not hype
“You have an EXCELLENT product. I am involved in the IT world as a trainer and a consultant, and I recognize a powerful, user friendly program when I see one, and yours is truly one of the best I have seen.”
“OneGreatFamily.com has been a tremendous help to me in my family research… I have discovered several dates that had eluded me, as well as finding some unknown ancestors that I didn't know existed. I also found 2nd & 3rd cousins that I never knew.”
“One person can't possibly do all of the work alone—they need help to speed up the work… The only way to do this is with your wonderful service.”
“I have found hundreds of relatives that I would have otherwise not been able to find… I love the merging technique that this website offers! The ancestry 'tree' or handprint is awesome.”
“The best thing is that the search program runs continuously and adds data automatically to your tree… I have recommended OneGreatFamily to friends of mine who are also interested in genealogy.”
“Wow! I never expected to go back 50 generations. I am thrilled with this program.”
“Thanks to OneGreatFamily and the power of technology I have found many living relatives… I have at present over 1,892 names and 653 families… and still growing!”
“You are all you say you are, and then some.”
Still comparing options?
If you are weighing record sites, desktop software, or disconnected uploads, ask whether the product merges obvious duplicates for you, searches while you sleep, and shows conflicts instead of hiding them. Those differences compound—especially when your line ties into a large shared trunk.
