Frequently Asked Questions
Enter the number of generations each person is from a common ancestor. For example, if both are grandchildren (2 generations), they are first cousins. If one is a grandchild (2) and the other is a great-grandchild (3), they are first cousins once removed.
It means how many steps away each person is from the shared ancestor. For siblings, it's 0 (same parents). For children, it's 1. For grandchildren, it's 2, and so on.
That means both are siblings (same parents). The calculator will output 'Siblings'.
'Removed' indicates a difference in generations. For example, first cousins once removed means one is a generation older or younger than the other.
