Probability of a Relationship Error
I just read again the 2016 article Green Temple Hunting by Mark M. Shepherd, viewable at FSFamilyTreeUserGroup, http://fsfamilytreeusergroup.com/training_by_topic.php (search the website for “Green Temple Hunting”). I understood Mark to say that starting with anyone born before 1800, there was a 96% probability of a relationship error between that person and any third+ cousins.
I tell people that come to the FamilySearch Center to be very cautious of relationships beyond fourth and fifth cousins that they have not proven themselves. Should I? Has anyone published an update to Mark’s analysis?
