HOW ARE YOU RELATED? A Family Relationship Calculator
Do you share a common ancestor with someone? Are you really cousins? Use this calculator to find the family relationship between two people who share a common blood ancestor.
Note: The calculator only works with a shared parent, grandparent, or great-grandparent. Relationships between nephews, aunts, and cousins are not calculated. Please refer to our Family Relationship Chart for those relationships.
