Have you ever been at a family gathering when someone mentions a “second cousin once removed” and felt completely lost? You’re definitely not alone. Many of us find the terminology around cousins and ‘removed’ relations confusing. But understanding these family relationships is surprisingly simple. In this easy guide, I’ll show you exactly how cousin relationships work, so you’ll never be baffled again!
The Mystery of 'Removed'
Let’s start with the biggest confusion: what exactly does ‘removed’ mean? ‘Removed’ simply describes how many generations apart two relatives are. Think of your family as arranged into clear, horizontal layers of generations. Your siblings and first cousins are in your generation. Your parents and their cousins are one generation above you. Your children and their cousins are one generation below you.
When someone is described as being “once removed,” it means they are exactly one generation away from your own. If someone is “twice removed,” they’re two generations apart. For instance, your first cousin’s child is your first cousin once removed. Your first cousin’s grandchild would be your first cousin twice removed.
It really is that simple. The number of times someone is “removed” is just the count of generations separating you.
Understanding Cousin Numbers & Building the Cousin Tree
Now that we’ve sorted out “removed,” let’s clarify the numbers that define cousins.
Cousins are numbered according to the ancestor you share:
First cousins share grandparents.
Second cousins share great-grandparents.
Third cousins share great-great-grandparents, and so forth.
Here’s a quick rule to help you:
Count how many ‘greats’ there are in the title of your shared ancestor.
Then, simply add one.
For example, if you share great-great-grandparents, that’s two ‘greats,’ plus one, meaning you are third cousins.
Building a Cousin Tree
Imagine yourself at the centre of your family tree. Above you are your parents, then grandparents, great-grandparents, and so on. Beside you are your siblings, and beside your parents are your aunts and uncles, and beside your grandparents are your great-aunts and great-uncles.
Your cousins branch off from the same level your aunts and uncles occupy:
Your first cousins branch from your aunts and uncles.
Your second cousins branch from your great-aunts and great-uncles.
Your third cousins branch from your great-great-aunts and great-great-uncles.
From there, you simply move down generations, adding “once removed,” “twice removed,” and so forth.
Applying the Rules & Working Upwards
Understanding cousin relationships works easily when looking sideways or downwards in your family tree. But what about when you look upwards? What about your grandmother’s cousin or your father’s second cousin?
Here’s a secret: relationships work both ways. To figure out relationships upwards, always start from the older person’s perspective. For example, to work out your grandmother’s cousin’s relationship to you, first identify how your grandmother sees them. Your grandmother’s cousin is her first cousin (they share grandparents). Now, consider yourself from your grandmother’s cousin’s perspective. You are their first cousin’s grandchild, meaning you are their first cousin, twice removed.
Let’s do another quick example:
Who is your father’s second cousin to you?
From your father’s perspective, this person is his second cousin, sharing great-grandparents.
From your father’s second cousin’s perspective, you are their second cousin’s child.
Therefore, you are their second cousin once removed.
It might sound complicated at first, but it quickly becomes second nature. Try it with different relatives, and soon you’ll master the technique!
Conclusion
Now you’re fully equipped to tackle any family reunion with confidence. Remember the two key rules: ‘Removed’ indicates how many generations apart you are, and cousin numbers depend on which common ancestor you share. Whether you’re looking at your cousin’s children or figuring out your grandmother’s cousin, the same simple logic applies.
