When information technology comes to cousinhood, the relationship possibilities are endless. Your number of grandparents doubles with each generation. Count back x generations, and that's 2,046 total ancestors, which means the cousin potential is exponential. You could have millions of them: fourth cousins, second cousins iii times removed, tenth cousins twice removed… we could go on.
Follow the steps on this cousin chart to figure out what kind of cousins yous are with a relative, including percentage of DNA matches and average shared centimorgans.
And with Dna testing, Facebook, online family trees and message boards that connect you lot to new cousins every twenty-four hours, y'all're bound to get curious about exactly how you're related. Good thing nosotros're here with this guide on figuring out what kind of cousins you are, based on degrees of separation from shared ancestors.
What makes someone a cousin?
The simple fact that you share an ancestor with that person. Merely to understand the intricacies of cousin relationships, you have to get this: Your ancestors are only the people in your direct line: parents, grandparents, great-grandparents and so on. Your ancestors' siblings are aunts and uncles (no matter how many greats you add)—non ancestors.
Just about any other claret relative who isn't your sibling, ancestor, aunt or uncle is your cousin. To determine your caste of cousinhood—showtime, 2d, third, 4th—you lot need to identify the ancestor y'all share with your cousin, and how many generations split up each of you from that antecedent.
First cousins
Your first cousin (sometimes chosen a full cousin, just usually but a cousin) is the child of your aunt or uncle. The almost contempo ancestor you and your first cousin share is your grandparent. You typically share 12.5 percent of your commencement cousin's Dna.
Second cousins
Your second cousins are the children of your parents' starting time cousins. Take a await at your family unit tree, and yous'll see that you and your 2d cousins have the aforementioned not bad-grandparents. Y'all typically share 3.125 percent of your second cousin's Deoxyribonucleic acid.
Tertiary cousins
Of course, cousinhood doesn't end there. You have likely also heard the term third cousin and wondered what that means. For third cousins, great-great-grandparents are the virtually recent common ancestor, and you share .781 percent of your Dna. You go the picture.
What is a second cousin once removed?
If you're puzzled over the expression "second cousin once removed" or "twice removed," you're not alone. Luckily, the answer is unproblematic: All cousins share a common ancestor. Your "degree of cousinhood" (second, 3rd, quaternary) depends on how many generations back that common ancestor is. Knowing this, y'all tin can brand your ain cousin computer.
Take your first cousins, who yous know are your aunts' and uncles' children. You all accept the same grandparents. Your 2nd cousins share a set of nifty-grandparents with yous, your third cousins accept the same great-corking grandparents, and so forth. And so your granddaughter and your sis's grandson would be 2d cousins, for case—they accept ii generations between them and the common antecedent (your parents).
How to summate cousin removes
"Removes" enter the picture show when two relatives don't have the same number of generations between them and their most contempo common ancestor. I generation difference equals one remove.
Let's get back to the previous example—say your granddaughter has a son. He has 3 generations betwixt him and the mutual ancestor (your parents), but your sis's grandson still has only 2 generations in-between.
And so they would be second cousins, simply once removed. Likewise, your grandparents' cousins are your first cousins twice removed considering of the 2-generation divergence from you to your grandparents. Your corking-great-grandparents are still the mutual ancestor.
Finding a recent common antecedent
First identify the about recent common ancestor for the ii relatives in question. And then detect each relative's human relationship to that ancestor on the sides of the nautical chart. Where the row and column meet, you'll find their relationship.

Double cousins
You may have heard people say they're double cousins. That's a special cousin category for the offspring of brothers- and sisters-in-police—for instance, your sister weds your husband's brother. Instead of sharing one fix of grandparents, as first cousins do, double cousins share both sets of grandparents. Every bit y'all might expect, double cousins have more than DNA in common than typical first cousins—well-nigh 25 percent.
"Kissing" cousins
Despite how it sounds, a kissing cousin isn't a cousin you marry. Rather, it's whatsoever distant relative you know well enough to kiss hello at family gatherings. At present we're begging the question: How close a cousin is too close to wed? States have unlike laws governing consanguineous marriages (and nosotros've heard all the jokes, so just stop correct now). Information technology's best to ask a lawyer about statutes for the state in question.
And while we're on the topic: Due to limited mobility in our ancestors' day, most of us have instances in our family trees of cousins who married, whether knowingly or unknowingly. That means you can be related to the same person in multiple ways.
Someone you're related to by union, rather than by blood, isn't your cousin. You might be in-laws, or your relationship might non have a name other than (we hope) good friends. You tin can read more than virtually collateral degree calculation — oops, we mean family relationships—in Dozens of Cousins past Lois Horowitz (Ten Speed Press) and Jackie Smith Arnold's Kinship: It's All Relative, 2nd edition (Genealogical Publishing Co.).
Tip: Remember that the shared DNA numbers shown in our chart are averages. Due to the random way Deoxyribonucleic acid is inherited, information technology'south possible y'all don't share whatever DNA with a given relative beyond about second cousins.
Collateral degree adding
Anthropologists call the process of figuring out cousin relationships "collateral degree calculation" (don't worry, we won't bound that term on you lot once again). Multiple removes and degrees of cousinhood can get complicated, merely you don't have to be a scientist to get it correct. Our nautical chart will help straighten out your cousin confusion; but follow the instructions for using it. For example, to figure out how you lot're related to your great-great-grandmother's sis'southward son, first determine the ancestor you share with him: your third-bang-up-grandmother. Find her on the chart, then count downwards one generation for the sister and one more to the sister's son. He's your showtime cousin three times removed.

How to Figure Out What Kind of Cousins You Are in 4 Steps
Meet Ann and Bea. They met at a genealogical club meeting and are trying to make up one's mind how they're related. Can you help them effigy it out?
ane. Identify the virtually contempo antecedent.
For Ann and Bea, allow's say it's James Eugene Harding, born in 1850.
2. Determine each person's relationship to that ancestor.
What kind of cousins you are depends on the most recent ancestor you lot share with your relative. Offset cousins share grandparents. Second ones share great-grandparents, third ones share bully-great-grandparents, and and so on. Add a "great" for each generation away from the common antecedent.
Ann and Bea determine that James is Ann's great-bully-grandad and Bea's fourth-great-grandfather.
3. "Equalize" the cousins at the level of the one closest to the mutual ancestor.
Equalizing the them at Ann'south level would brand them tertiary cousins.
4. Add one "removed" for each deviation in generations between the them.
Ii "greats" carve up Ann and Bea—they're third cousins twice removed.
Things go trickier when you're talking almost being "removed." Each "removal" signifies one generation of departure betwixt the two. Your first cousin's child is your start cousin once removed. Your beginning cousin'due south grandchild is your beginning cousin twice removed.
