DNA evidence of N-4 from the Nolan DNA Surname Project Lineage II and Kit #56134 from the Windham Family DNA Project give a high probability of a common ancestor through an extramarital event or adoption based on the following information:
1. Edward MacLysaght established that the O'Mulgeehy, O Maolghaoithe, McSwyne, Sweeney family of Ireland became Wynne or Windham.
2. The 33 of 37 Y-DNA marker match between N-4 of the Nolan DNA Surname Project and Kit #56134 from the Windham Family DNA Project have three possible points of occurrence: 1. In 1574, both families owned castles in Galway, Co. Ireland and would have socialized together; 2. Both represent Herenagh Families of Donegal Co. Ireland. Herenagh meaning land typically converted into donated church property; and 3. Both families were represented in the early history of Isle of Wight Co. VA in the early 1640's.
NOLAN - WINDHAM
PROBABILITY & TIME TO MOST RECENT COMMON ANCESTOR.
96.81% Probability of a Shared Common Ancestor within 24 Generations:
24 generations multiplied by 15 (Years in a Generation) = 360 years.
24 generations multiplied by 25 (Years in a Generation) = 600 years.
91.44% Probability of a Shared Common Ancestor within 20 Generations:
20 generations multiplied by 15 (Years in a Generation) = 300 years.
20 generations multiplied by 25 (Years in a Generation) = 500 years.
2006 minus 1597* = 409 Years.
2006 minus 1643* = 363 Years.
* 1597 - THOMAS NOLAN purchased Enniscrone Castle Co. Sligo.
* 1643 - JOHN NOWLIN living in Isle of Wight Co. VA.
