Understanding family relationships can feel like solving a complicated puzzle. It is a challenge for many people, given the diversity of definitions like “first cousin once removed.” This is made even more complicated by the continuous growth and changes of families over generations. A study claims that 60% of the people surveyed have a hard time identifying and distinguishing the members of their extended families.
This two-part article will explain cousin terminologies, like the meaning of “removed,” and terms such as great-grandparents and great-aunts. IF you are working on your family tree or figuring out how to introduce yourself to a distant cousin at a family reunion, this guide will help.
Let us look deeper into the family matrix.

Basics of Direct Ancestry
Family relationships can be confusing, but direct ancestry is the easiest place to start. Understanding how generations are connected helps make sense of family trees and long-lost relatives. Whether you’re diving into genealogy or just trying to explain how you’re related to a distant cousin, a solid grasp of direct ancestry lays the foundation for everything else.
Parents and Grandparents
Our closest family relationships are the ones we grow up with – parents and grandparents. Your parents are your immediate ancestors, directly passing down their DNA to you. They are considered the first generation before you. Simple, right?
Grandparents take things one step further. Each person has four biological grandparents – two for each parent. When was the last time you heard someone call you a mini version of one of your grandparents, saying, “You look just like your grandfather!” or “You have your grandmother’s eyes.” There is a reason for all of that, and it is because you have inherited a lot from them.
But grandparents are not just about genetics – they help in the shaping of traditions, tell important family stories, and instill core values into the family structure. A study says that more than half of all grandparents offer some form of regular care to their grandchildren, which proves that grandparents have an active role in the family structure.
Immediate Family Connections
Other than parents and grandparents, the immediate family includes siblings who share the same parents as you. Moreover, aunts and uncles, who are your parents’ siblings, also form part of the immediate family. Other members of the close expanded family are first cousins, who are the children of your uncles and aunts.
This group builds the base of your family tree network. If you are unfamiliar with the concept of genealogy, try to trace out these relationships for starters. One simple way to remember it is that your parents’ siblings are your aunts and uncles, and the children of those aunts and uncles are your first cousins. The pattern continues as the family tree grows.
Great-Grandparents and Beyond
Let’s go back one more generation. Your great-grandparents are the parents of your grandparents. Everyone has eight great-grandparents, which means that your family tree grows tremendously in the reverse direction. Great-grandparents are often the figures who shaped family migration stories, cultural traditions, and historical ties.
Go back another generation, and you reach great-great-grandparents. At this point, you have 16 direct ancestors in this tier alone. Each additional generation doubles the number of direct ancestors, making it clear why tracing family history can become so complex.

Understanding the Generational Hierarchy
The generational hierarchy is simple in structure but can feel overwhelming when you try to apply it to real life. Think of it this way:
- You (first generation)
- Parents (one generation above you)
- Grandparents (two generations above you)
- Great-grandparents (three generations above you)
- Great-great-grandparents (four generations above you)
The pattern continues, with each additional “great” representing another generational step. In case you ever lose track, family trees can be useful visual tools.
Let’s now move on to the more complex relationships within the family after having explored the direct family tree.
Aunts, Uncles, and Extended Family
Family trees do not solely extend upward; they also spread outward. Extended family is made up of aunts, uncles, and cousins who are central to the structure of a family. Whether they are the relatives you interact with at every family holiday or the relatives that you are new to discovering, understanding these relationships gives clarity to the connection all individuals have.
Aunts and Uncles
These are the family members that are directly above you in the family tree. A maternal uncle is your mom’s brother, and a paternal aunt is your dad’s sister. This is easy to understand, right? Once blended families, step-relatives and half-siblings come into the picture it gets more interesting.
A biological aunt or uncle shares the same parents as your mother or father, while a step-aunt or step-uncle is related to you not by blood but in law. A half-aunt or half-uncle is someone who shares only one parent with your parent. which means you have a lower genetic link to them as compared to a full aunt or uncle.
Despite these differences, aunts and uncles serve as secondary parents, caregivers, and, in many cases, the best storytellers. Studies have shown that an overwhelming 60 percent of aunts and uncles remain engaged actively in the lives of their nieces and nephews, offering emotional support, mentoring, and companionship.
Great-Aunts and Great-Uncles
Rising up the family tree, we run into great-aunts and great-uncles. These are the siblings of your grandparents. For example, your great-aunt may be the sister of your grandfather, and your great-uncle may be the brother of your grandmother.
Because some families traditionally refer to their extended relatives as “aunt” or “uncle” out of respect and affection, these titles can be confusing. However, knowing how they connect across the family tree aids in genealogical research.
Fun fact: In some cultures, the term “great” is omitted and people instead use grand-aunt and grand-uncle. Although both are right, the terms “great-aunt” and “great-uncle” are predominant in English-speaking countries.
Understanding Cousins
If you have ever felt puzzled as to why someone is called your “second cousin once removed,” relax because that is an understandable confusion. Family relations can be complicated, but when organized, they’re a lot easier to comprehend.
First Cousins – Sharing Grandparents
Your first cousins are the children of your aunts and uncles. As with all other types of cousins, they share the same set of grandparents which makes them the closest within the cousin category.
For instance, if your father’s sister has a child, then that child is your dad’s nephew – and that nephew is your first cousin. You probably experienced part of your childhood with your first cousin, went to the same family events, and maybe even shared some physical features because of genetics.
Second and Third Cousins – How the Generations Expand
Move one generation further, and you reach second cousins. These are the kids of your parents’ first cousins. Rather than spending time with the same grandparents, second cousins have the same great-grandparents.
As we move further along, the next level is third cousins, who share great-great-grandparents. The pattern continues with fourth, fifth, and even more distant cousins, each one adding another generation of separation.
Now that we have explored this basic terminology, let’s tackle something like “second cousin once removed.” What is this concept of relatives being “removed” in relation to you? In Part 2 tomorrow, we’ll dive into this.
