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)
