    Most 37 marker matches are no longer a Y67 or Y111 match when they have had a Y111 test which means that the most distant common ancestor in the direct paternal line is from many thousands of years ago. The only way you can know if the common ancestor is from less than 2,000 years ago is if you were to convince your match to upgrade or if you paid for his upgrade. If he is a match at Y111 then you can get with a haplogroup admin to help get a better estimate on when the common ancestor likely lived.
    Since the thread is active. My take on TiP reports at 37 markers or less is you use it to check for very low probability results on MRCA. If its 0 or in the 20th percentile by 24 generations, that's a line you can probably safely ignore. That TiP can let you check STR marker levels higher than what you match at also makes it very useful, as you can have SNP matches who fail to fall within the matching criteria for Y25+. So being able to do a 67/111 marker TiP report on a 25 marker match is much more useful than just looking at the 25 marker GD data.

      A person that FTDNA identified as a close male relative, with a similar surname at 111, and I have encouraged two others with closely similar name and genetic distances of 2 and 3 at 67 to take the 111 test. We have found that both of these people are at distance 3 at 111. One lives in Switzerland, one in Alsace. We all signed up for the Big Y500 Test in late December and were pleased to be informed by FTDNA that we were being upgraded, free of charge, to the new Big Y 700, since our results have not yet come in. So 4 of us, with close genetic distances at 111 and similar last names, only a letter or two apart, are awaiting what the 700 test will provide. To be continued .....
      Great news for your family, and your more distant cousins it looks like on this one. Hopefully BigY helps shed more light on the connections involved.
