Removed
When the word "removed" is used to describe a relationship, it indicates that the two people are from different generations. 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.

Double Cousins
If two brothers in one family marry two sisters from another, and each couple has a child, the offspring are double cousins. The addition of the word
double to the first cousin term is the result of the number of common grandparents that are shared in this case. Regular first cousins share only one set of common ancestors, while double first cousins share all lineal and collateral relatives.
