Ügyek - Ügyek has been disconnected from his descendants?

Not only from some descendants but also from most of his ancestors by the looks of it, 2 months ago he still had hundreds of ancestors including Huns and Mongolians.
I am loosing track of what is happening, so many people "cleaning up" family trees...
is it like "ethnic cleansing" one chooses who he/she or she wants to be related to ancestry vise and then cleans out/deletes ancestors/ people he/she dont want to be related to...

He's my 42nd GGF, I think if everyone that traces this far down should follow Ugyek's profile, that might help rebuild some connections, and hopefully take off from there.
