# About us

The Y-DNA results that we have seen so far indicate that R1b-DF104 and DF105 phylogenetic nodes are the starting clades (Y-haplogroup) of our research. The median age estimate for R1b-DF104 places it ~36 AD. The conclusion to start with the R1b-DF104 and Df105 clades is based on the numerous Connachta surnames in the publicly available R1b-DF104+ test results that genetically correlate with the historical Irish genealogies and annals for the most part. As of May 2019 AD, there are almost 1200 known R1b-DF104+ men.We are a dedicated group of people interested in the heritage of those family groups who historically descend from Conn Cétchathach, AKA Conn of the Hundred Battles. From the Irish annals, he was a High King of Ireland who lived ~125 AD. From him descend many of the important medieval dynasties of the northern half of Ireland, which was known as the Leath Cuinn, or the Half of Conn. We use modern surnames, Irish genealogies, and Y-DNA sequencing results to attempt to fit what the science of genetics reveals into the heritage of the historical Dál Cuinn.
Two of the most well known Dál Cuinn dynastic groups are the Teóra Connachta and the Uí Néill. The Teóra Connachta were composed of the Uí Briúin, the Uí Fiachrach, and the Uí Ailello; this last dynasty either dying out or being exterminated in the first millennium AD.
As of August 2022 AD, there are over 2050 known R1b-DF104+ men.
