German Y-DNA Match

My father finally has a Y-DNA match at Family Tree DNA.

Both my father and the person who is a match tested 37 markers.  His surname is not Lutter.

(Another person tested 111 markers, but there are too many differences to qualify as a reportable match beyond 12 markers.)

FamilyTreeDNA did not report this new person as a match at the 37 marker level.  When I compared the actual numbers, they have five differences out of 37.  The values are off by only one for each difference.  Without testing additional cousins from these lines, we have nobody else to compare to determine if this man and my father might share a common direct paternal ancestor.

This other person has roots in Germany.  He can trace his direct paternal line to about 1830, which is how many years back I can get on my Lutter line.  His line originated in Treppeln, Brandenburg.  Mine was from Scheibe, Thueringen.  Treppeln is a few miles west of the current border with Poland and is about 180 miles northeast of Scheibe.  If I have the correct Treppeln.
