I'm not sure everyone here follows the U106 discussion group so I wanted to post this here. Iain was speculating about the age and location of SNPs FGC11784 and FGC42045. Since almost everyone who has a kit in this group comes down through those SNPs I thought it might be of interest. You can always look at the file of the S6881 Group Tree that I have posted in the files section that shows the order of the SNPs if you want to see how close or far you are from these two SNPs. Here is what he said:
"
Please do understand that what is below is *very* speculative.
?
R-FGC11784 is quite a large clade for its age. Its downstream participants are strongly British, and specifically English: 52% of R-FGC11784 men list "England" or "UK" as a country of origin, compared to 16% of R-U106 overall. By comparison, only 3% list "Scotland", "Wales" or either Northern or Republic of Ireland, compared to 9% of R-U106 overall. This suggests migrations that only affected England, rather than the rest of the British Isles.
?
European R-FGC11784 records include Germany, the Netherlands, Denmark, France and Italy (8% of testers). This low percentage is partly due to our American testing bias, but the European percentage is also low compared to R-U106 overall (20%). While this could suggest a British origin for R-FGC11784, the majority of these European results appear in the upper (basal) clades of the R-FGC11784 phylogenic tree, and it's not until the major clade R-FGC42045 that the clade becomes very significantly British (2% of testers are European, 53% are English/UK). R-FGC42045 testers probably share a common British ancestor, dating back to the first millennium AD, but British testers from elsewhere in R-FGC11784 may have a different entry point in history.
?
The distribution of European testers has moderate significance. They are distributed around the same North Sea coasts as many Germanic tribes, but notably we have yet to find any Scandinavian results. We'd expect these to make up about a quarter of continental testers. This may be due to a lack of continental testers, but probably indicates a small Scandinavian R-FGC11784 population, and a continental European origin for R-FGC11784, somewhere in a Germanic population. The lone Italian family is common in clades which experienced a significant post-Roman migration.
?
Based on this information, if I had to make a guess, I would be thinking Anglo-Saxon invasions of England. At face value, the evidence here seems fairly clear-cut for that. However, there's always a danger in using averaged evidence across a whole haplogroup, based on scant and heavily biased data, to try and pick out evidence for a particular family. Not everyone follows the norm, so please don't take this as the only option, and be aware that future evidence may change these conclusions."
