Cousin Calculator


Introduction

Figuring out relationships between two people can be extremely confusing, but the chart below should help.

For more information see Cyndi's List: Cousins and Kinship.


How it works

Step 1: On the top row, find the relationship of one person to the common ancestor. Follow the column straight down.

Step 2: On the left hand column, find the second person's relationship to the common ancestor. Follow that row straight across.

The relationship will be found where the row and column intersect.
