Seems to me the answer depends on whether you can afford the additional test. Confirming that the two men have the same Y DNA profile would remove one possible source of uncertainty in the genealogy. If they don't match, you have a new set of genealogical problems to explore. If they do match, you are no closer to breaking through the brick wall in Poland, but at least you would know it is the right wall.

He has no very close matches with 37 markers--they come to a distance of 2 at 25 markers. He belongs to the appropriate Y project, which has an updated map here: https://www.google.com/maps/d/viewer?mid=1Wev1XRrmyzQl5v12SRiIp8hmqK8&hl=pl& ll=51.031354920586296%2C19.846628250000094&z=4 . My father's first cousin has done Family Finder and is clearly related just as expected. So far we have not bothered to test his Y, on the theory that it is likely to be exactly the same, although the possibility does exist that there is a mutation either in his line or my grandfather's. Thoughts on whether to get his Y tested? He and other surviving males descended from my great-grandfather are the only people we know of in the lineage--we haven't discovered my great-great-grandfather's parents or siblings, as he first appears in the records we have seen as a parent in Polajewo in the Posen/Poznan region of what's now Poland. In other words, great-great born in the 1820s is now the top brick wall ancestor as all the other lines go into the 18th century or earlier. Sifting through all the neighboring parish records seems like our next and daunting step to trace him. I have probably asked this question before, but as prices drop and list membership changes a bit, it can't hurt to pose it again.
