Marriages between people who are related is more common than you might think. Unlike what many people think, their offspring are not doomed to birth defects or medical problems.

How are second cousins related to third cousins?
Since the second cousins (the parents of the third cousins) may have known their common ancestor personally (their great-grandparents), they are more likely to raise their children to know their more extended family. I have a few second cousins on my dad’s side of the family who I knew fairly well growing up.
Is it possible for third cousins to share no DNA?
It’s possible for third cousins to share absolutely no DNA, yet still be “genealogically” related. As you can see, there is a wide range of cMs that third cousins can share with each other. This can cause a few problems when you are looking at a cousin match and trying to figure out how they are related.
How are you related to your 4th cousin?
You may discover many of your 4th and 5th cousins—and sometimes even your 8th or 10th cousins.

Breakthrough science. Breathtaking discoveries.
