How to export a GEDCOM file

A GEDCOM (.ged) is a standard genealogy file format that records individuals, families, births, deaths, and marriages. Both Ancestry and FamilySearch can export your tree as a GEDCOM, which this tool will parse entirely in your browser — nothing is sent to a server.

From Ancestry.com

1. Sign in at ancestry.com
2. Open the family tree you want to export
3. Click Tree Settings (gear icon near the top of the page)
4. Scroll to the bottom and select Export Tree
5. Click Export and save the .ged file to your computer

The resulting file includes all individuals and family relationships in your tree. For very large trees this can take a moment to generate.

From FamilySearch

FamilySearch has removed their export feature. If you want to export your tree, connect to a service such as Ancestry.com and export the GEDCOM file from there. When you do this, FamilySearch may only hand over 4 generations.

Notes on coverage

The tool scans the GEDCOM for men with overlapping marriages and generates a plural family chart for each one it finds. The quality of the results depends on how complete your tree's marriage and death dates are — the more dates recorded, the more accurate the concurrent-marriage detection will be.

If your tree is missing death or divorce dates, some marriages may appear to overlap when they did not. Supplementing with known dates from historical records will improve accuracy.
