Family relationship chart

The full cousin chart in one table. Find your generation from a shared ancestor down the side, theirs across the top, and read off exactly how you're related.

Row = your generation from the shared ancestor. Column = theirs. Scroll sideways on a small screen.

Only one exact relationship to work out? The cousin calculator takes the same two generation counts and gives you a plain-English explanation, and it covers relationships further out than this chart shows.

How to read the chart

Pick the one ancestor you and the other person both share (a grandparent, a great-grandparent, and so on). Count how many generations down from that ancestor each of you sits, then find your count on the left and theirs along the top. The cell where they cross is your relationship.

The diagonal is same-generation cousins

The highlighted cells running corner to corner are pairs at the same generation: two grandchildren of the shared ancestor are first cousins, two great-grandchildren are second cousins, and so on, one degree higher each row down the diagonal.

Off the diagonal is aunts, uncles, and "removed" cousins

Anywhere the row and column generations differ, one of you is one or more generations closer to the shared ancestor. In the first row or column, that gap gives you an aunt, uncle, great-aunt or great-uncle relationship. Everywhere else, it gives you a "removed" cousin: the degree comes from whichever of you is closer to the ancestor, and the removal counts how many generations separate you from them.

Once you've mapped how everyone in the family connects, Family Tree Studio turns the whole tree into a print-ready poster you can hang or give as a gift.

Questions

Good to know.

How do I use this chart?
Find your own generation from the shared ancestor down the left-hand column, and the other person's generation from that same ancestor along the top row. The cell where your row and their column meet is your relationship.
Why does the chart stop at fifth cousins?
Past fifth cousins the terms keep following the same pattern (sixth cousins, seventh cousins, and so on) but the shared ancestor is so far back that almost nobody tracks it that precisely. If you do need an exact term further out, the cousin calculator on this site covers up to sixth cousins, seven times removed.
What if the relationship I need isn't a clean grid match?
This chart assumes you can each count your own generations back to one shared ancestor. If that's straightforward, the chart gives the answer directly. If your case is unusual, the cousin calculator on this site asks for the same two generation counts and works out the exact term, including relationships further out than the chart shows.
Is a half-cousin different from what's shown here?
The degree and removal terms are identical, people just add "half" in front. A half first cousin shares only one grandparent instead of a full shared couple, but is still worked out from the chart the same way.
Can I print this chart?
Yes. The print button above the table opens your browser's print dialog with a version sized to fit a single page, with the navigation and footer removed.
Does this page track or store anything?
No. It's a static table with no forms, no inputs and no tracking. The only script on the page opens your browser's print dialog when you click the print button.

Now put the whole family on one page.
