Paper trails can lie, DNA does not lie. At least we can all claim to be descended from Charlemagne. 
I say about 5% of our ancestors we have traced may not be biological ones. Infidelity is as old as time itself, and was relatively common 200 years ago like today.
whilst i agree when you get further back it is biologically probable that there are biological ancestors with whom you share no DNA.
Campbell, Dunn, Dickson, Fell, Forest, Norie, Pratt, Somerville, Thompson, Tyler among others
