CATHCART PROJECT UPDATE:
May 2006 - Y-chromosome DNA testing has identified two unique Cathcart haplotypes (DNA signatures). Further testing of Cathcart surnamed males will assist in identifying the MRCA (Most Recent Common Ancestor) for each group.
July 2006 - Participants #2 and #3 have upgraded their tests to the recently debuted 67-marker panel, and match exactly on all 67 markers! Referencing Family Tree DNA's Genetic Distance Chart the match indicates a 95% probability of the common ancestor occurring within the last six generations.
Feb 2007 - New results posted for participants #1 and #4 and they match Group 1. An upgrade to 37-markers or 67-markers is recommended for participant #1 to further refine the match.
The 67-marker upgrade is recommended for all participants.
