COUSINS

     You know what your cousin (or FIRST COUSIN (1C)) is, and how they are related to you. (Your cousin is the child of your aunt and uncle; your aunt or uncle is a sibling to one of your parents).

     Now, if your cousin has a child, that child is a FIRST COUSIN ONCE REMOVED (1C1R) to you, i.e. one generation removed from being a first cousin.

     If you have a child, your child is a SECOND COUSIN to your first cousin's child.

     If your first cousin has a grandchild, that grandchild is a FIRST COUSIN TWICE REMOVED (1C2R) to you, and a THIRD COUSIN to your grandchild.

     It all keeps working the same way. Undoubtedly, you have a 12th Cousin somewhere, and their grandchild is a TWELTH COUSIN TWICE REMOVED to you.
