Laborde is a French surname heavily concentrated in the French Pyrenees
Why the “J1b type” Ley, from Devon, England is a “singleton” and the same can be observed in relation to Laborde, from France ?
It seems that the “J1b type” is thinly scattered around Western Europe with the two unrelated cases in Devon and probably in the French Pyrenees ?
Why there’s a small frequency but at a regular rate of the “J1b type” in Western Iberia, mainly in the Portuguese populational stock ? I can find the “J1b type in almost all Brazilian regional samples at the frequency of 0,5%, from the West to the East, from the North to the South of Brazil ? It seems that the “J1b type” was present since the foundational stock in the Minho, the cradle of the Portuguese population around the year 1100, so the advance of the Portuguese frontier in the Reconquista and in the conquest and colonization of Brazil would spread the “Portuguese J1b type” at a regular rate.
Another point is the estimation of the TMRCA (Time to Most Recent Common Ancestor) of the “J1b types in Iran, Portugal, France and in England ? The TMRCA is practically the same around 1500 years (more or less), as we can see in the Mcgee Y-utility
The question is how the “J1b type”, a small clade found only in Eastern Anatolia-Georgia-Northern Iran and the Caspian adjacencies arrived in Western Europe around the year 400 ?
The Arthurian Legends had the steppe component from the Caucasus, probably a group of haplotypes from that part of the world could arrive in Western Europe around the period of the Fall of the Roman Empire, a window of opportunity linking the Atlantic with the Caspian Sea, not only the possible “J1b types”, but also Caucasian types of the G haplogroup and others could had arrived in that conjuncture. The fact is that the “J1b types” had a common ancestor somewhere close to Northern Iran 2000 years ago because the structure of the matches between the Western European “J1b types” and the Iranian “J1b types”. The TMRCA is quite close to 1500-2000 years and there’s a starlike type of expansion of all “J1b types” since then. So some of the legends in Western Europe could perhaps be connected with the Iranic-type of knights and mercenaries present in Western Europe in that time ? Some wrote about the Sarmatians but the Alans could be a good candidate for the extinct Iranic groups that could reach Western Europe by the fall of the Roman Empire as the source of the Western European “J1b types “ ?
