Instructions:

  1. Select two people in your family and figure out which ancestor they have in common. For example, if you chose yourself and a first cousin, you would have a grandparent in common.

  2. Look at the top row of the chart (in grey) and find the first person's relationship to the common ancestor.

  3. Look at the far left column of the chart (in grey) and find the second person's relationship to the common ancestor.

  4. Move across the columns and down the rows to determine where the row and column containing these two relationships (from #2 & #3) meet. This box is the relationship between the two individuals.

    Good Luck!
