Four Big Ys for an American family: September 7, 2018 I-L233 tree

Click here to download our September 7, 2018 tree for I-L233

This update shows two new Big Ys for an American family, all four men belong to the I-BY55516 haplogroup. There are now two SNP defined branches of this family: two men belong to the I-Y94204 haplogroup and two belong to an unnamed branch defined by the variant hg38:12926290 C to A. Note: the information about this variant is preliminary and needs to be confirmed with further testing or more Big Y results.

If you compare this September 7 tree to our 2018-07-15 tree, you will see how the new Big Y results changed the placement of Y94204 and BY55516 and discovered the new variant at 12926290.

This update also shows an update for another branch of I-L233. Thanks to the YFull analysis we learned that two men share the Y54081 SNP as shown in red. FTDNA refers to this branch as I-BY33207, but BY33207 is found in the DYZ19 repeat region which is sometimes considered unsuitable for phylogeny.
