These participants appear to have a supporting paper trail back to the 1600 time period. http://www.familytreedna.com/public/WindhamFamily/default.aspxhttp://www.familytreedna.com/public/WindhamFamily/default.aspx Kit # 18393form this R1b1b2a1b4 Group. http://www.worldfamilies.net/surnames/n/nolan/http://www.worldfamilies.net/surnames/n/nolan/ N-4 and N-30 from thisR1b1b2a1b4Group.

Mathematically they look like this:
100 years 200 years 300 years 400 years 500 years 600 years 29.50% at 100 years 69.39% at 200 years 89.57% at 300 years
96.89% at 400 years
99.15% at 500 years
99.78% at 600 years Meaning that the common ancestor of these men was nearly certainly within 400 years ago, or less. Best Regards
