Relationship Terms
Sometimes, especially when working on your family history, it's handy to know how to describe your family relationships more exactly. The definitions below should help you out.

Cousin (aka "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.

Parallel and Double Cousins
Parallel cousins are the children of two brothers or two sisters.  Example: Two SMITH brothers marry two JONES sisters -- their offspring will be double first cousins.

Regular first cousins share only one set of common ancestors, while double first cousins share all lineal and collateral relatives. Also, these SMITH-JONES children would be parallel (or ortho) first cousins.

The chart below is helpful in determining the relationship between two people.

bullet

This chart is based on the system used by courts and most genealogical societies. The numbers at the top and left side represent the generations away from the common ancestor.

bullet

To identify the relationship between any two people, first identify the common ancestor of the two people.

bullet

Locate the box in the upper left corner for the common ancestor. Follow the column straight down to find the relationship of one of the two people to the common ancestor.

bullet

Across the top row of the chart, find the relationship of the second person to the common ancestor. It may be helpful to pencil-in the names of the two persons for whom relationship is sought. 

bullet

Where the projected column and row intersect is the box that identifies their relationship.

bullet

The highlighted boxes show persons of the same generation.

bullet

"Removed " indicates that the two persons selected are not of the same generation.

bullet

This chart may be extended in either direction to identify more distant relationships.
