Instructions for Using Kinship Chart:

This chart is used to determine kinship between two people.

1) Determine the common ancestor.

2) Determine his/her relationship to the first person. Find that relationship in the row along the top of the chart. Draw a straight line down the chart from that relationship.

3) Determine the relationship of the common ancestor to the second person. Find that relationship in the row along the left side of the chart. Draw a straight line across the chart from that relationship.

4) Where the two lines intersect is the degree of kinship.

For example, the kinship between someone’s great-great grandparents and a second person’s great-great-great grandparents is Third Cousin, Once Removed. If two persons share the same grandparents, they are first cousins. If two persons share great-great-great grandparents, they are fourth cousins.
