Starting at Ancestry DNA page and My Tests, click on link Find Matches. You should see all close and remote matches by name and their DYS markers and alleles. At top-right corner of Matches page, click on link Groups. At lower-right of next page (DNA Groups), enter the surname in the box marked Search for Individual and click Submit.
When I enter Sayres, only Paul appears in the participants list. At far-right click on View link below Profile. You may not have this option unless you are managing more than one Y-DNA account. For me, this option appears because of the Compare feature. When I click on Compare button, Paul's and my Y-DNA are illustrated, the results stacked on top of each other for marker-marker comparison.
I am going to send to your gmail account a screen capture of the above. And thanks for the Ancestry Tree invite...coincidently, I went to school with Terry Snodgrass, of Orange, VA...perhaps one of your cousins?
