Understanding cousin relationships in your trees

Do you ever wonder what the terms "second cousin" or "first cousin once removed" mean?


Look no further than this cousin chart to settle any debates!


But first, let's define what a cousin is.

Cousins share a common ancestor that is at least 2 generations away, such as a grandparent or great-grandparent.


This means that you and your siblings are not considered cousins since your parents are only 1 generation away from you.


The number associated with your cousin (e.g. second cousin) has to do with how many generations away your common ancestor is.


For instance, second cousins share a great-grandparent (3 generations) while third cousins share a great-great-grandparent (4 generations).

To determine the number of "greats" in your common ancestor's title, simply count and add 1 to find out what number cousin your relative is.

However, keep in mind that this trick only works if you are both the same number of generations removed from the common ancestor.


If you and your cousin share a common ancestor but call them something different, use the term "once removed" to indicate that you are separated by one generation.


The number before "removed" represents the number of generations you are separated from your cousin.
