- Your first cousins are those people in your family who have two of the same grandparents as you, i.e., they are the children of your aunts and uncles.
- Your second cousins are the people in your family who have the same great-grandparents as you, but not the same grandparents.
- Your third cousins have the same great-great-grandparents, and so on.
When the word “removed” is used to describe a relationship, it means that the two related people are from different generations:
- You and your first cousins are in the same generation (both two generations younger than your grandparents).
- Your mother’s first cousin is only one generation younger than those same grandparents, so your mother’s first cousin is your first cousin, once removed.
