Y DNA-7 matches on 67 markers with zero deviation

My Uncle has 6 matches on 67 markers with zero deviation. Three of the men seven men can verifiably be traced to the same couple born in 1711, and none of them share autosomal DNA. Does this suggest all of the men descend from this same couple or am I reading to much into the results?

Certainly looks like a common ancestor.  You can't say couple.

Also, you can't pin down the generation of the common ancestor.  Could be the 3 testers descend from 3 brothers in the 1711 generation.  This is where you have to rely on the paper trail.

You wouldn't expect any shared autosomal DNA at that distance.
Thank you!

Right, the male only...To be more specific: Newman Perkins b 1711 had 6 sons, John, Ebenezer, Uriah, David, Samuel & Oliver. Through reserach 3 of our Y DNA matches trace back to his sons Oliver and Ebenezer. So, that's what I've been thinking, since there's not any deviation at this level the others would also descend from one of their brothers. Unfortunatley we have brickwalls and a couple of NPE's.

Three of the testers have tested out to 111 markers and at that level the deviation increases to 2. I'm not sure what that changes, if anything. Maybe I should have started with that. This has been quite a learning curve and amazing that we have so many matches.
I hope you will add their results to mitoYDNA.org and get them to join WikiTree.
I'll add my uncle and ask the others, hopefully they will be willing.
