Understand The Difference Between Second Cousins And Cousins Once Removed

Save this for your next family reunion.

Remembering the difference between a “second cousin” and a “cousin once removed” is one of those facts that I have filed away in my brain as non-essential. I think I know the difference, but then I get fuzzy on the details.

Luckily I now have a handy chart to bookmark in my web browser so that I never forget again.

You’ll find it useful, too, especially if you’ve been invited to a family reunion this summer.

This chart was designed by Alice J. Ramsey in 1987, but her advice still stands today.

Here’s how to use the chart: Start from the “Self” box, and then trace your way to the relationship you are trying to name.

Remembering what my mom’s cousin’s children are in relation to me is always a tricky one for me. Using this chart, I can see that they are my second cousins. And their kids? My second cousins once removed. Their kids? Second cousins twice removed.

Once Removed—What Does It Mean?

This chart gives us a visual depiction of what “once removed” really means. It’s easy to see that you and all of your cousins—even those second and third cousins—are in the same generation. But when you get into different generations, that’s when it comes “once” or “twice” removed—what that really means is one generation removed, according to the chart.

“For example, your mother’s first cousin is your first cousin, once removed. This is because your mother’s first cousin is one generation younger than your grandparents and you are two generations younger than your grandparents, ” according to an article on Genealogy. “This one-generation difference equals ‘once removed.’ Twice removed means that there is a two-generation difference. You are two generations younger than a first cousin of your grandmother, so you and your grandmother’s first cousin are first cousins, twice removed.”

Once you get your brain to stop spinning, just look at the chart. It will help you understand.

Why Are We So Interested In Our Roots?

As you know, there are seemingly dozens of websites and services you can use to trace your family’s history—we’ve all heard of Ancestry.com and 23andMe. But why are we so fascinated with our family tree?

Scientists say we have an instinctual urge to learn more about our family members because we share the same genes.

The deep-rooted interest in our ancestry is partly shaped by evolutionary forces, Beverly Strassmann, a University of Michigan anthropologist, told LiveScience. Humans care about family members because they share some of our genes.

“People can pass on their genes either by having their own offspring, or by helping their kin to reproduce,” Strassmann said.

In other words, there’s a reason all your relatives ask incessantly about your love life and when a baby will come into the picture—and that reason is biology.

Beyond that, our interest in genealogy may also be derived from royalty. People needed to understand their ancestry to justify their position in society or on the throne.

“The fascination goes back to antiquity,” Eviatar Zerubavel, a sociologist at Rutgers University, told LiveScience. “Royalty, for example, and nobility were very obsessed with creating genealogies that would link them to heroes.”
