2019-12-22 tree for I-L160

Click here to download our 2019-12-22 tree for I-L160

This tree shows the following updates:

  • a new I-V1686 branch, it's parallel to the large I-CTS11851branch. The families in this branch have Mexican/Spanish and English paternal ancestry. V1686 and other V series SNPs in this branch were first discovered in an anonymous I2 sample in Trombetta et al: Regional Differences in the Accumulation of SNPs on the Male-Specific Portion of the Human Y Chromosome Replicate Autosomal Patterns: Implications for Genetic Dating. The article and supplementary material can be found here: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0134646
  • a new I-Y83613* branch which contains some families from County Kerry in southwestern Ireland, they have English and Irish families. They share a MRCA who lived a few hundred years ago with the more specific I-FT18829 branch which contains the large Allen family from Virginia, USA
  • a new I-BY205153 branch (English origin). The two samples in this branch aren't closely related to each other and we can't find any other families that might belong to this branch based on STR marker patterns
  • a third sample in I-A19455
