Family Relationship Chart

To find the relationship between two people, first determine the common ancestor you share and your relationship to the common ancestor: grandchild, great grandchild, etc. Pencil in the common ancestor’s name, if it helps. n Choose Person #1’s relationship to that ancestor from the top row of boxes, e.g. “child.” n Choose Person #2’s relationship to that ancestor from the left column of boxes, e.g. “grandchild.” n The box where the two intersect identifies the relationship between the two people in this case: Niece/Nephew.
