How to Remove a Cousin
Most people have a good understanding of basic relationship words such as "mother," "father," "aunt," "uncle," "brother," and "sister." But what about the relationship terms that we don't use in everyday speech? Terms like "second cousin" and "first cousin, once removed"? We don't tend to speak about our relationships in such exact terms ("cousin" seems good enough when you are introducing one person to another), so most of us aren't familiar with what these words mean.
Sometimes, especially when working on your family history, it's handy to know how to describe your family relationships more exactly. The definitions below and the chart to the left should help you out.
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. For example, C and D are first cousins. They are in the same generation, so have the same color on the chart.
Your second cousins are the people in your family who have the same great-grandparents as you., but not the same grandparents. For instance, while K and L are first cousins, K and H are second cousins.
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. (X and T are third cousins, while a and h are fourth cousins.)
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. (On the chart, the generations are labeled by numbers and also color-coded.) For example, your mother's first cousin is your first cousin, once removed (C and J or D and H). 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 (for instance, E and W).
