Click here to download our 2021-02-28 draft tree for I-Y5455

This is our first update to the I-Y5455 tree since June 2020. We show a new branch called I-FT246786, it contains two of three samples from the Cox family from Ireland (Isles-C2). 

We show a new branch for the Casey family from Ireland (Isles-C2), and a new I-BY37223 level in Isles-C1. These are based on Big Y results from several months ago.

Minor new branches in "Disles": 2021-02-18 draft tree for I-L621

 Click here to download our 2021-02-18 draft tree for I-L621

This tree shows several updates in the "Disles" branches (Disles is L621+ but CTS10228-).

I-Y81561 is a new branch which contains two American samples, one with southwestern Germany origin and one with Irish or Scottish origin. I-FT48648 contains two closely related samples from southern Sweden, it is the sibling branch of I-Y81561.  The Swedish and German Big Ys were completed in 2020 or earlier but the Irish-American Big Y-700 is recent. This tree also shows additional FT series SNPs shared by all samples (at the I-BY54321 level). FTDNA and YFull's trees are outdated, they don't include the new information from the  Irish-American Big Y-700. 

***Update 22 February 2021***FTDNA has added a new branch called I-S12964 for the Irish/Scottish and German samples. Our tree shows this branch as I-Y81561. We didn't include S12964 because it's in the centromere region and the German sample has a small number of reads at this position, we will add it to our next update.

I-BY193188 is a new branch, it contains some members of the Irish-Scottish American Gibson family. This tree also shows additional upstream SNPs in this part of the tree.

CTS4533 is a SNP that occurs high in the tree. We show it provisionally as equivalent to S19848 because kit B173953 has no CTS4533 reads in his Big Y-500 results.
