Haplogroup X for me is associated with the archeologically verified Viking and Irish artefacts known to be found in North America.

I would be very happy to find that I have inherited this distinction.

Paul, I would like to know where you acquired that link of Haplogroup X to Vikings in America.  NatGeo is connecting X  to Native Americans mostly... or originating  somewhere in Asia/Siberia and making their way to North America.

Yes, my X2 is from mtDNA... I don't care where you get your X from... just interested in knowing if there are Xs on the site.

Interesting link:

"Researchers who study aging have long suspected that mitochondria play a role in aging. Mitochondria are responsible for processing metabolized food particles into adenosine triphosphate, which fuels vital cellular processes. They're also involved in cell growth and differentiation. But the ability of mitochondria to function properly seems to decline with age.

Understanding the reason for that decline—and the genes that might control it—has been challenging. Mitochondria have their own DNA, which is passed down from the mother only. This unique chromosome has variations, called haplogroups. Nine such haplogroups have been well characterized in people of European descent, Scott says. But only haplogroup X was found to be prevalent among healthy aged people in the University of Miami study."The advantage of working with a homogeneous population is, you're reducing the variances that can be associated with the environment," Crawford says. Mennonites and Amish "don't drink, don't smoke. Most do some sort of physical activity. They don't sit around working on a computer all day.""

A number of important insights into the peopling of the New World have been gained through molecular genetic studies of Siberian and Native American populations. While there is no complete agreement on the interpretation of the mitochondrial DNA (mtDNA) and Y chromosome (NRY) data from these groups, several generalizations can be made. To begin with, the primary migration of ancestral Asians expanded from south-central Siberia into the New World and gave rise to ancestral Amerindians. The initial migration seems to have occurred between 20,000–15,000 calendar years before present (cal BP), i.e., before the emergence of Clovis lithic sites (13,350–12,895 cal BP) in North America. Because an interior route through northern North America was unavailable for human passage until 12,550 cal BP, after the last glacial maximum (LGM), these ancestral groups must have used a coastal route to reach South America by 14,675 cal BP, the date of the Monte Verde site in southern Chile. The initial migration appears to have brought mtDNA haplogroups A-D and NRY haplogroups P-M45a and Q-242/Q-M3 to the New World, with these genetic lineages becoming widespread in the Americas. A second expansion that perhaps coincided with the opening of the ice-free corridor probably brought mtDNA haplogroup X and NRY haplogroups P-M45b, C-M130, and R1a1-M17 to North and Central America. Finally, populations that formerly inhabited Beringia expanded into northern North America after the LGM, and gave rise to Eskimo-Aleuts and Na-Dené Indians. Am. J. Hum.

Lola... from that post wouldn't you say that the haplogroup X is ONLY found on the mtDNA and hasn't presented itself on the NRY up to this time????  That's what it looks like to me... it kind of threw me when you asked if I meant only mtDNA.  Maybe I misunderstood what you meant by asking.

Two traceable inheretences give two views on a persons ancestry.  From the relative speed of mtDNA crossing physical boundaries, it does seem a constant practice of men importing brides rather than accepting strange men in their society.
