Relationship Chart

To determine a kinship between yourself and someone else:

Determine your own relationship to a common ancestor by using the top row (horizontal).

Find the other person's relationship to the same ancestor by using the left column (vertical).

Read down and across to find the box where the two intersect — this is your kinship.

*Example: Your First Cousin's child is your First Cousin Once Removed
(being one generation removed from the original cousinship)
