@Yeehaw0 I don't think marrying a distant cousin is really 'incest'. A first cousin could be a bit problematic, a sibling/parent is surely incest, but a distant cousin is, well, distant. And it should be noted that the likelihood to have genetic problems even with the most harmful form of incest (parent/child) is still relatively low.

The only problem is if there are many generations marrying cousins one after the other, then you will start to see serious problems. It's the piling up that amplifies the problem
