For example, You and your First Cousin share a grandparent as a common ancestor. You and your Second Cousin share a great grandparent as a common ancestor. * You and the child of your First Cousin are First Cousins, once removed. * You and the child of your Second Cousin are Second Cousins, once removed. * You and the grandchild of your First Cousin are First Cousins, twice removed. * You and the grandchild of your Second Cousin are Second Cousins, twice removed.
