I&#x27;m sorry, could you explain in a bit more detail?  It sounds like what you&#x27;re saying is that your sister&#x27;s husband signed up for 23andMe and sent in his DNA sample.  Then, 23andMe said &quot;based on your DNA, we believe another of our members is likely your niece, here is her contact info...&quot;.  Then, your sister&#x27;s husband contacted this person (the potential niece), and after some chatting it seemed likely that your sister&#x27;s husband&#x27;s brother was indeed the girl&#x27;s biological father, and this was then later confirmed with additional DNA testing.<p>If this is in fact the story, doesn&#x27;t this seem like an invasion of privacy on the part of 23andMe?
