Cousin chart.

Find the ancestor you share. Across the top, what they are to you; down the side, what they are to the other person. Where they meet is how you're related.

Why do cousins get "removed"?

The number (first, second, third) counts how far back the shared ancestor is for whichever of you is nearer to them, minus one. "Removed" counts how many more generations the other person is away. So first cousins share grandparents, second cousins great-grandparents, and your grandmother's first cousin is your first cousin twice removed.

Uncles, aunts, nephews and nieces

The second row and column aren't cousins. When the shared ancestor is one person's parent, the other is their uncle or aunt (one generation apart), great-uncle or great-aunt (two), and so on. Read the other way, they're nephews and nieces. The chart says "uncle/aunt" because it doesn't know whether they're a man or a woman; the calculator does if you tell it.

FAQ

Questions

How do I read a cousin chart?

Find the ancestor you share with the other person. Go along the top to what they are to you, and down the side to what they are to the other person. Where the column and row meet is your relationship.

What does 'once removed' mean?

That you're one generation apart. Your first cousin's child is your first cousin once removed, and so is your parent's first cousin.

What is a third cousin?

Someone who shares great-great-grandparents with you, but no nearer ancestors. Your grandparents and theirs were first cousins.

Can I print the chart?

Yes. Use your browser's Print, or save it as a PDF. The page prints without its menus.
