Thanks Jim! Match #2 has no matches (besides me) over 6cM matching our segment.  My 5.0-6.5cM segment matches that triangulate with match #2 match her between 3-5.3cM - should I contact those 5 testers?  I had not done that because of the segment size.    I have a known 3rd cousin (match #3) from this line that doesn't triangulate in common with match #1.  When I compare match #1 & 3 in the chromosome browser I find 3 possible matches.  Each of those are about 3cM on 3 different chromosomes (ch 8, 11 & 12).  One of those segments also matches #2 1.85cM.  Does this have any significance in this situation?  Neither match #1 or 3 will upload to gedmatch. Thanks again, Casey
