·       Notes-write on individual match page and view on match list


·         Pedigree and Surnames, common ancestors, Can "expand tree" and on next page "view full tree"

·         Shared matches are 4th cousin or closer to self and your match. Cutoff is 20cM.  Very important for identifying networks of matches.  Provided even when the match has no tree. 

·         
Using CentiMorgans
·         CentiMorgans are a measure of length and strength of matching segments.  The larger the cM, the closer your relationship.
·       Use DNAPainter.com Shared Matches tool to find the probability for different relationships.
·         There are no cases of second cousins not having a matching segment.
