Group Description

Our project goal is to identify the lineages of common ancestors by building family trees and branches using STR markers.

The Case Study methodology is based on the work of Dr. Anatole Klyosov. He has documented his calculations for determining TMRCA (Time to the most recent common ancestor). We build a phylogenetic tree with the yDNA results and then run them through Anatole's calculations to see if the yDNA results are within a reasonable range (80+%) or within 250-300 years. If yes, this is considered a lineage.

The work being done for the 4466&South Irish project can be reused for any base Haplotype. It has expanded to research when the 4466 SNP occurred in the phylogenetic tree that includes both their ancestors.

We are creating a methodology and framework to help volunteers build their own STR family trees and branches. Everyone can share information and ask questions in this forum.

The documentation for the building of family trees and branches will be written so anyone and everyone can start their family tree from scratch; see http://southirish.com/results.htm for the TMRCA Case Study Framework that helps to build family trees and branches.
