Cousin (a.k.a "first cousin")

Your first cousins are the people in your family who have two of the same grandparents as you. In other words, they are the children of your aunts and uncles.

Second Cousin

Your second cousins are the people in your family who have the same great-grandparents as you., but not the same grandparents.

Third, Fourth, and Fifth Cousins

Your third cousins have the same great-great-grandparents, fourth cousins have the same great-great-great-grandparents, and so on.

Removed

When the word "removed" is used to describe a relationship, it indicates that the two people are from different generations. You and your first cousins are in the same generation (two generations younger than your grandparents), so the word "removed" is not used to describe your relationship.

The words "once removed" mean that there is a difference of one generation. 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. 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.

Relationship Charts Simplify Everything

Now that you have an idea of what these different words mean, take a look at the chart below. It's called a relationship chart, and it can help you figure out how different people in your family are related. It's much simpler than it looks, just follow the instructions.

Instructions for Using a Relationship Chart

1. Pick two people in your family and figure out which ancestor they have in common. For example, if you chose yourself and a cousin, you would have a grandparent in common.
2. Look at the top row of the chart and find the first person's relationship to the common ancestor.
3. Look at the far left column of the chart and find the second person's relationship to the common ancestor.
4. Determine where the row and column containing those two relationships meet.
