Map & timeline

Possible overlaps

Times and places where people from different family trees could have been together - widened to cover the gap between two known dates, since we rarely know the exact day someone moved on.

Specific Collisions in Space and Time (Citywide)
General Collisions (Statewide)
Birth

Death

Other places lived

If they moved, add each date and place - shown on the map as its own stop along their life.

Where do the trails meet?

Genealogy Mapper plots separate paper-trail ancestries - each its own color - on a shared map and timeline, so you can spot the times and places where people from different family trees could plausibly have crossed paths.

1. Add a family tree One color per paper trail you're following - split it further into more family trees any time.
2. Add people Upload a GEDCOM file, paste rows from a spreadsheet, or fill people in by hand - birth, death, and any other places lived.
3. Watch the map Play through time and see when two different family trees' dots land in the same place at once - a possible lead worth checking.
