DNA and common ancestors

I haven’t been doing much research lately and I tend to gravitate toward genetic research these days if I do. DNA reports are interesting and my father’s report is very interesting since though he is majority Dutch (well classified as French/German), he shares a common ancestor with some Irish guy named Niall of the Nine Hostages.

I really thought the Irish came more from my mother, but interestingly, according to 23andme, it comes more from my father. So my father’s haplogroup starts with haplogroup A, where all of everyone’s paternal lines can be traced to one man, the common ancestor of haplogroup A. Other male-line descendants lineages died out except the one guy, and his lineage gives rise to all other haplogroups today.

Then his paternal line stems from a branch called R-M269, a very prolific paternal lineage across Eurasia. These farmers pushed east into Central Asia and into the Caucasus Mountains. Some reaches the steppes above the Black and Caspian Seas. Eventually, a new steppe culture called the Yamnaya was born and they spilled into Siberia and into Central Asia, to the west they pushed into the Balkans and central Europe. Their descendants spread from central Europe to the Atlantic coast. The spread of my father’s haplogroup in northern Ireland and Scotland was probably aided by men like Niall of the Nine Hostages.

One website says Niall may be the big daddy of Ireland. His actual name in Irish was Niall Naoi Noigiallach and the myth is that he was descended by an unknown number of generations from Conn Ceadcathlach aka Conn of the Hundred Battles, who may have lived in the middle of the second century and was the first high kind of Ireland. Research has revealed that as many as three million men living today may carry his y-DNA signature. y-DNA is only traceable through men, women do not have y-DNA. Niall got his name by taking nine key hostages, including Saint Patrick, in raids on his opponent chieftains in Ireland, Britain and France to cement his power. He is said to have twelve sons.

You never know what you’ll find when you check out your DNA!
