What is my cousin's cousin to me?
It depends on which side of your cousin's family they come from. If they are a cousin through the grandparents you share, they are your first cousin as well, or your own sibling. If they are a cousin on your cousin's other parent's side, you share no ancestor with them and aren't related by blood at all.

Is my cousin's cousin related to me?+
Only on the side you share. On the other side, your cousin's cousin shares no ancestor with you, so no blood connects you.
How do I tell which side they're on?+
Find the grandparents you and your cousin share. If they are also your cousin's cousin's grandparents, that person is your first cousin (or your sibling). If not, they come from the other side.
