Hub DNA Matches
 

Best Mate has several matches who have no shared matches themselves, but masses (often twenty or more) of other DNA matches match to them (and nobody else)

Can anyone explain why there is this clumping? I have yet to get any of them to reply, to work out what the connection might be.

Could it be that they're all below ancestry's threshold for shared matches apart from the "hubs"?

What is a "hub"?

PS: Admin - side issue/suggestion - should we have a dedicated DNA board for questions?

My own term, Kit.

Say I have 20 low grade DNA matches. They all are matches with X, but not with anyone else.

So X is clearly significant. But I don't know how!

And it is usually the rule that even if X has a tree AND replies to emails, we cannot find that significance.

This really bugs me.

Thanks for the explanation.

I hope you can solve for X eventually.
