Most of us have a rough sense of where our family “came from,” but it stays a list of county names in a spreadsheet. This tool turns that list into a picture: every ancestor placed at their birthplace, with lines running down the generations and converging on you. After a few early revisions, I really like how this tool has evolved.
You can start three ways. Upload a GEDCOM from your tree software and pick your home person, and the tool lays out the ancestral line for you — parents, grandparents, and back as far as your file goes. Or start from a spreadsheet, using the blank template it provides. Or simply start typing names into an empty list, which is often the fastest way if you are working from one particular line.
Either way, you get an editable list with a slot for every ancestor, labelled by relationship, so the gaps are as visible as the names. Putting someone on the map takes one click: type the place and let it find it, or click the exact spot yourself. This is especially useful if you know the exact creek or farm where your ancestor was born. Nothing is placed until you place it.
As the map fills in, each grandparent’s line takes its own color, so you can see at a glance which branch went where and turn the others off to follow one line at a time. The timeline plays the map forward through the generations, or backward from you toward the oldest ancestor, revealing each birthplace as its year arrives. That playback is what turns a static map into a story — you watch the family converge on one place, or scatter from it. An “At a glance” panel does the math for you: how many generations you have covered, the range of birth years, how far the farthest ancestor was born from your home person, and the radius that half of them fall within. That last figure surprised me about my own family.
There are six background maps to choose from, including satellite imagery and a topographic map that shows creeks, churches and cemeteries, plus a county-lines overlay you can switch on over any of them — worth having, since a county line determines which courthouse holds the family records. If you would rather not publish the names of living people, one setting keeps your parents off the map and runs the lines from your grandparents straight to you.
When you are finished, download a shareable page: a single file holding your map, which you can email to a cousin or put on a website. That same file opens again in the builder whenever you want to keep working, so it is both the finished piece and your backup.
