Jane's Genealogy Jigsaw
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.
