For the off spring to a couple to be "safe" the children must have less then 25% shared DNA. After 2 generations of fresh blood mating from different families, its safe for a couple to hve kids even if they have a common ancestor.

The Pies and the Apples are distant cousins (really distinct), Marble and Big Mac don't need to worry about anything here because their common ancestor was many generations ago. So even if their related, its fine.

People ho always fret over "incest" often aren't fully aware of what it covers. It basically just means you can have kids with your uncle/aunt, 1st cousin, second cousin (some cultures go as far as 3rd cousin), mother/father, grandfather/grandmother, half-brother/half-sister. (Step-brother/step-sister would not count as your not blood related normally).
