ยท         EXAMPLE: A "first cousin" is your relationship to your parent's niece or nephew, because you are both grandchildren of a common ancestor.

o    Your relationship to your cousin's child is "first cousin once removed", because you added one generation to the relationship.

o    However, the relationship between your child and your first-cousin-once-removed would be "second cousin", because they are both great-grandchildren of a common ancestor.
