If you’re like many people, you may have heard the phrase “9th cousin once removed” and wondered what it all means. It sounds complicated but, in reality, it is a simple concept that just requires some understanding of how family relationships play out over time. Read on to learn more about what this term means and why it is used in genealogy research.
The Basics of Family Relationships
Before delving into exactly what 9th cousin once removed means, let’s first take a look at the basics of family relationships. Most people are familiar with basic terms such as mom, dad, sister, brother, and so on. But when it comes to extended family members, things can get a bit more complicated. That’s because we use specific terms to describe our relationship with them—terms like aunt and uncle or first cousin. So what exactly do those terms mean?
An aunt (or uncle) is the sibling of one of your parents; first cousins are the children of your parents’ siblings; second cousins are the children of your parents’ first cousins; third cousins are the children of your parents’ second cousins; and so on. As you can see, these relationships become increasingly distant with each generation.
What Does “9th Cousin Once Removed” Mean?
Now that we’ve established some basic family relationships, let’s talk about what 9th cousin once removed means. To understand this term, you need to understand two concepts: degree and removal. Degree refers to how distant two people are from each other in terms of generations—in this case, nine generations apart—and removal refers to whether they are from the same generation (no removal) or different generations (once removed).
Therefore, 9th cousin once removed describes two people who are nine generations apart and from different generations—for example, if one person is your great-great-great-grandparent’s grandchild and the other is their great-great-great-grandparent’s grandchild (nine generations).
Conclusion:
Understanding family relationships can be tricky but having an understanding of key terms like 9th cousin once removed can help make things easier. Knowing how to correctly use these terms will also help you better understand family trees and genealogy research in general.

Q: What does 9th cousin once removed mean?
A: The term “9th cousin once removed” refers to a distant cousin relationship between two individuals. It indicates that they are ninth cousins and that one of them is one generation younger than the other.
Q: How do you determine the cousin relationship?
A: The cousin relationship is determined by counting the number of generations between two individuals to their common ancestor. For example, if both individuals share the same great-grandparent, they would be considered second cousins. The term “ninth cousin” indicates that the common ancestor is nine generations away.
Q: What does “once removed” mean?
A: The term “once removed” in the context of cousin relationships means that one individual is one generation younger than the other. For example, if your grandparent and someone else’s grandparent are siblings, you would be “first cousins once removed.”
Q: What does “twice removed” mean?
A: The term “twice removed” refers to a cousin relationship where one individual is two generations younger than the other. For example, if your great-grandparent and someone else’s great-grandparent are siblings, you would be “first cousins twice removed.”
Q: How do I calculate the number of generations between two cousins?
A: To calculate the number of generations between two cousins, count the number of ancestral generations from each individual to their common ancestor. Subtract the smaller number from the larger number to determine the difference in generations.
A: Yes, cousins can share multiple common ancestors. This often occurs when their families have intermarried or have a long history of relationships within a particular community or region.
Q: What is the significance of knowing the cousin relationship?
A: Knowing the cousin relationship can provide insight into your family’s ancestry and connections. It can help you understand how you are related to other individuals and potentially uncover shared DNA matches.
Q: How does the term “ninth cousin once removed” differ from “ninth cousin twice removed”?
A: The term “ninth cousin once removed” indicates a cousin relationship where one individual is one generation younger than the other. In contrast, “ninth cousin twice removed” indicates a cousin relationship where one individual is two generations younger than the other.
A: The cousin relationship generally impacts the amount of DNA shared between two individuals. Closer cousins, such as first cousins, share more DNA due to their closer genetic connection, whereas more distant cousins share less DNA.
Q: Can cousins be from completely separate family branches?
A: Yes, cousins can be from completely separate family branches. In some cases, they may discover their cousin relationship through genealogical research or DNA testing. This often happens when there is a distant common ancestor that was previously unknown.
