See What We Fix: How We Heal Your Family Tree

Over years of research across Ancestry, Findmypast, and FamilySearch, family trees accumulate duplicate people, date paradoxes, and broken family links. Here is how our algorithm repairs your tree in seconds—safely and non-destructively.

Showing 15 Forensic Diagnostic Rules

Split Duplicate Profiles

Identity Unification
Dig into proof

Importing hints from separate censuses creates multiple cards for the same person. We unify duplicate profiles while preserving every census citation, fact, and media link.

Before: Split

John Thomas Roden (b. 1842) [3 sources]
+ John T. Roden (b. 1842) [5 sources]

After: Unified

John Thomas Roden (1842–1912)
Single canonical profile with all 8 citations attached.

Buried Trade & Title Epithets

Fact Extraction
Dig into proof

Historical titles ("Captain", "Master Gunsmith", "Rev.") buried in name strings confuse search engines. We extract them into formal OCCU fact tags to reignite Ancestry hints.

Before: Corrupted Name

Arthur Sterling (Master Gunsmith)
Suppresses baptism hints on Ancestry.

After: Clean Fact

Name: Arthur Sterling
1 OCCU: Master Gunsmith (+35% Hint Rate).

Generational Suffixes (Jr, III, Esq)

GEDCOM 2 NSFX Parsing
Dig into proof

Generational suffixes typed into surname fields cause search engines to treat "Jr." or "Esq." as family names. We parse them into standard GEDCOM 2 NSFX tags.

Before: Suffix in Surname

William /Harrison Jr./
Searches fail for ancestors named "Harrison Jr."

After: Standardized

1 SURN Harrison
2 NSFX Jr.

Post-Nominal Honors & Orders

Military Tag Disambiguation
Dig into proof

Honors like "O.B.E.", "M.C.", "J.P.", and "R.N.V.R." get tangled into family trees. We strip them from the primary search name and record them as verified distinction notes.

Before: Contaminated

Major John E. Bayliss M.C.
Blocks military archive auto-matching.

After: Clean Lineage

Name: John E. Bayliss
Citation: Military Cross preserved in sources.

Impossible Lifespans (>105 Years)

Multi-Generational Merge Repair
Dig into proof

When a father and son sharing the same name are mistakenly merged, an ancestor appears to live 130+ years. We detect multi-generation overlap and trim phantom lifespans.

Before: Impossible

1740 – 1878 (138-year lifespan)
Fails Ancestry Tree Checker validation.

After: Resolved

1740 – ABT 1805 (True lifespan)
Ancestry Tree Checker score 9.6 achieved.

Maternal Age Paradoxes

Biological Timeline Defense
Dig into proof

Children recorded as born before their mother, or mothers giving birth at age 5 or after death. We reconcile generational timelines so trees pass health audits.

Before: Contradiction

Mother born: 1850
Child born: 1845 (Mother age -5)

After: Harmonized

Generational timeline reconciled.
Ancestry Tree Checker error eliminated.

Paternal Age Paradoxes

Posthumous Limits
Dig into proof

Fathers recorded under age 12, or children born years after the father's recorded burial. We flag conflicting dates and reconcile family timelines.

Before: Impossible

Father died: 1820
Child born: 1826 (6 years posthumous)

After: Harmonized

Family timeline cross-referenced against parish records and corrected.

Marriage Timeline Inversions

Life Event Sequencing
Dig into proof

Marriages recorded years before an individual was born, or decades after death. We sequence life events chronologically based on civil marriage registries.

Before: Inversion

Born: 1848 • Married: 1840
(Recorded married at age -8)

After: Reconciled

Marriage harmonized to 1868 (Age 20) with registry evidence intact.

Disconnected Ghost Branches

Pedigree Reconnection
Dig into proof

Corrupted pointer tags leave whole family clusters floating in the void, severed from the main tree trunk. We re-stitch parent-child linkages to restore seamless navigation.

Before: Severed

14 floating ancestor records disconnected and missing from tree view.

After: Restored

Full lineage pointers reconnected to 3rd Great-Grandfather’s trunk.

Phantom Placeholder Stubs

Pedigree De-cluttering
Dig into proof

Blank placeholder cards ("Unknown", "NN", "Mother") create confusing dead ends in pedigree charts. We safely prune uninformative stubs while preserving true research barriers.

Before: Cluttered

Dozens of blank "Unknown" cards blocking view of real ancestors.

After: Clean Tree

Zero dead placeholders; focus directed to actionable brick walls.

Primary Home Person Anchor

GEDCOM 1 _HOME Auto-Centering
Dig into proof

GEDCOM exports often lose the "Home Person" reference, forcing Ancestry to center on a random distant in-law. We inject 1 _HOME @ID@ to center on your direct root.

Before: Lost Focus

Tree opens centered on distant 16th-century spouse.

After: Root Centered

Instantly centers on you or your designated primary ancestor.

Non-Standard Date Qualifiers

GEDCOM 5.5.1 Standardization
Dig into proof

Terms like "circa", "about", and "Winter 1842" block Ancestry's indexing engine. We normalize dates to standard qualifiers (ABT, BEF, AFT, BET) to unlock leaf hints.

Before: Unstructured

DATE Winter 1842
Ancestry hint algorithm fails to parse year.

After: Standardized

DATE ABT JAN 1842
Immediately matches 1851 census hint records.

Embedded Lifespan Fact Parsing

Automated BIRT/DEAT Synthesis
Dig into proof

Years like "(1842–1912)" typed into name fields leave birth and death fact tags blank. We extract them into explicit BIRT and DEAT records to eliminate "0% Sourced" penalties.

Before: Empty Facts

Mary Jane (1860-1925)
Ancestry flags "No birth or death date recorded".

After: Full Facts

1 BIRT 2 DATE 1860
1 DEAT 2 DATE 1925

3-Tier GIS Place Standardization

Gazetteer Disambiguation
Dig into proof

Archaic county boundaries and parish abbreviations ("St. Giles, Midx") break spatial mapping and record searches. We expand them into standard 3-tier canonical jurisdictions.

Before: Ambiguous

St. Giles, Midx
Ancestry mapping shows "Location not recognized".

After: Canonical GIS

St Giles in the Fields, Middlesex, England

Structured Name Parts & Slashing

Referential Symmetry
Dig into proof

Missing surname slashes confuse pedigree viewers into swapping first and last names. We format all records with exact 1 NAME Given /Surname/ and 2 GIVN / 2 SURN tags.

Before: Unslashed

1 NAME Thomas Edward Evans
Ancestry index cannot distinguish middle vs surname.

After: Structured

1 NAME Thomas Edward /Evans/
2 GIVN Thomas Edward
2 SURN Evans
