Thus far no subgroups of closely related project members have been identified.  Four YDNA haplogroups have the most results: R-M269 (aka R1b), I-M150, I-M253, and J-M172.  Unfortunately, none of the individuals within these groups are likely to be related to each other within the past ten generations.  If any relationships are identified in the future, we will add new subgroups to identify these.
