Because “somewhere in the family” is not a relationship.
Genealogy has a funny way of introducing you to people you know are family… but you’re not quite sure how.
This calculator takes the guesswork out of those moments. By simply entering how many generations separate each of you from a shared ancestor, it translates the math of family trees into real-world relationships—like first cousin, great-aunt, or second cousin twice removed.
It’s especially helpful when branches start to spread, surnames change, or extended families weave together across generations. Suddenly, that “mystery relative” has a place—and a name you can actually use at the next reunion.
