"This is yet another case where we need to go back to one basic principle: DNA alone can never be enough to prove a genealogical relationship. In every single solitary case, bar none, without fail, we are going to need at least one more piece of information to be able to prove a genealogical relationship.

I’ve said this before,2 but it bears repeating. What seems, on the surface, to be compelling DNA evidence is in fact compelling DNA evidence — but it’s compelling if and only if it’s properly interpreted.

In W.P.’s case, there are at least three possible scenarios at play:

1. The paper-trail cousins haven’t opted into the matching system at AncestryDNA.

2. W.P. isn’t O.M.’s child.

3. The father of the paper-trail cousins isn’t O.M.’s brother"
