Y-DNA match across a 6 generation common paternal ancestor.

  
 
Modern Science at work. Y-DNA is passed from father to son. i.e. If the Y-DNA matches for two people then they have a common male ancestor somewhere in time. In this case there is 37 Marker match at the J2b2 level.

 
  Samuel Kumarakulasingham Devadason and Sereno Barr-Kumarakulasinghe have a 37* marker match of their Y-DNA. They both share a common ancestor, Sangarapillai Tilliampalam, 6 generations removed based on the genealogical tree from www.ceylontamils.com**. Sangarapillai Thilliampalam is the son of Irrumarapunttaya Thilliampalam Kumarakulasinghe.

The 37 marker results confirm thats the haplogroup is J2b2. Based on the 67 marker test its most likely the deep haplo group is either J2b2c or J2b2d.

So, what does this mean.
a) This means that Samuel and Sereno have a 90% probability of sharing a common ancestor within 12 generations based on the 37 marker tests. See here for description of the Y-DNA inheritance.
b) The Hapologroup J2b2 implies West Asian/Middle East origins less the 5000 years ago. This page gives very simplified explanation of the origins of the J2b2 haplo group.



**Kudos to Rohan Titus and Tishan Mills for their great site www.ceylontamils.com which enabled the tracking of the common ancestor. Yes, quite a bit of the data/information on this site is from www.ceylontamils.com

*The 67 marker test results are on the way.
