Another old Irish family: 2020-01-17 tree for I-Y11222

Click here to download our 2020-01-17 draft tree for I-Y11222

This tree shows a branch called I-Y63713, it contains the Healy family from southwestern Ireland, and some other families that probably had Healy paternal ancestry several generations ago. Based on the number of SNPs/variants in each sample, the common ancestor of this family lived many hundreds of years ago.

For example, the most recent sample (indicated in red) has 15 private variants and he shares another 4 variants with only one other sample. That's 19 variants that occurred after the MRCA of the 4 samples, and this MRCA was very likely named Healy or its equivalent in the Irish language.

According to this tree, the two I-Y63713* samples don't share any downstream variants. But they share the rare STR marker value DYS458=12 with each other and with some other Healy men. And if they both upgrade to Big Y-700 I think there's a good chance that they will find some shared variants.
