The Tree Score · free
A family tree is only as good as its evidence. Upload yours and we weigh every parent-and-child link on the records behind it, show you which are Probably right and which only Possibly, and name the record that would prove the rest.
Your tree file (.ged, or the .zip Ancestry gives you) from Ancestry, MyHeritage, Family Tree Maker, RootsMagic or any other program. How do I get my file?

What we catch
A tree can look complete and still join a child to the wrong parents. Our grader reads every link the way an editor reads a proof.
Anne Hale daughter of Margaret Hale
The tree saysMargaret born 1598Anne born 1659
As recorded, Margaret was 61 when Anne was born.
Usually two women of the same name, merged into one.
To settle it: The parish baptism register, which names Anne's parents.
William Abbott son of Mary Abbott
The tree saysMary died 1801William born 1803
As recorded, William was born two years after his mother died.
A wrong date, or the wrong Mary.
To settle it: The 1810 census and Mary's burial record.
Johann Kessler son of Peter Kessler
The tree saysSource: an online family tree
No record anywhere names Peter as Johann's father. The tree it was copied from cites nothing either.
Copied links travel fast and are rarely checked.
To settle it: Johann's baptism in the church book, which names his father.
Real kinds of error our grader flags. Names and details changed.
What your report shows
Not a single score that punishes a big tree. Three measures — how far back, how complete, how sure — then the pedigree to explore, link by link, and the few records that would raise your tree the most.

Father’s side on the left, mother’s on the right. Each segment is the link from a child to that parent.
Ranked by their share of you: a parent is half your ancestry, a grandparent a quarter. Upload the record and two readers check it against the link.

Nothing in the file speaks to this link yet.
Jonas Avery as the father of Susanna Avery
One source supports this link: the census shows the child in the household.

Your tree file
Every family-tree site and program can save your tree as a GEDCOM file, the standard format. Pick where your tree lives.
A GEDCOM file holds names, dates, places, relationships, notes and source citations, the parts we grade. Photos are not needed.
Prove it, then certify it
Free. Every link weighed on the records your file cites. Nothing kept.
Photograph the baptism, the census page, the certificate. Two independent AI readers check it against the link. Free.
A dated credential from you to an ancestor, every link verified, at a permanent address anyone can check. See a sample.
One-time. Reissued free for a year as you prove more. Our grade under our published standard, not a lineage society’s approval.
Your file is read, graded and discarded in the same moment. We keep nothing from it: no names, no dates, no copy of the tree. The report goes only to you. A record you upload to prove a link is read by our AI provider and not kept. Only if you certify a line do we keep that line: the ancestors who have died, their grades and the kinds of record behind them.
Living people are never shown publicly. Grades describe evidence, not identity, and are not legal determinations of kinship.
