I do not know too much about Genetics and the implications to my family, but I've done a YDNA test for my paternal line.
For the immediate paternal past I know I come from a UK Family - Caucasian - with a traceable history back to the late 1700's in Britain. My surname is listed as being Sardinian in origin,in a book of UK Surnames that came out in 1912 (can't remember the name of the book!!)
I remember reading somewhere that "Sard" has been in the UK since the Domesday book. I know my Surname exists in Italy and the UK most strongly, but also in France, Spain and Scandinavia.
My YDNA test says I belong to Haplogroup D - an old lineage found mostly in Tibet, The Andaman Islands, the original Japanese and small drabs of Mongolia..!!
Is this a common thing..? Most research says these are the main places where this Halogroup exists, and even then only in small pockets..!!
Is it likely to be a mistake ? I may get a second test...
But for the meantime I can only guess. Perhaps generational movements through maybe Genghis Kahn/Kublai Kahn, Attilla the Hun (knowing that it was predominantly Halplogroup C - Maybe some Haplogroup D's were in the hordes?) or migration along the Silk Road...? I'm really at a loss...
Bearing in mind the Italian/Europe/UK surname
But maybe even through Turkey and the Turkic populations there - but they are pretty much Haplo C and in small concentration)...
Maybe I'm thinking too recently, and there were movements earlier on - but I don't know much about that..
I'm at a loss..!!
Anyone with any suggestions would be welcome...!!
Thanks for any help
