    My aunt’s kid is my cousin. My cousin’s kid and my kid are second cousins.

    It’s essentially finding the most recent common ancestor. My cousins and I share grandparents. Second cousins share great-grandparents, and so on.

    “Once removed” and such refers to generational differences. So, my first cousin’s kid is my first cousin once removed, and my kid’s second cousin.
