It's easier to use YSTR as a tool since the recent search upgrades. I've
used it in the past by "manually" searching on various n-step variations
& was struck by the matches in Spain, Columbia, & Portugal. The database
is still "small" relative to what we need for detailed migration analysis.
My 12-marker sequence FTDNA DYS sequence is:
I'm I*, so says FTDNA. I have 9 exact YSTR matches:
Finland 5 / 399
Gotland, Sweden 1 / 40
Leipzig, Saxony 1 / 573
Riga, Latvia 1 / 145
Western Norway 1 / 64
With the 1-step mutation DYS393 13->12, I get:
Bulgaria 1/ 122
Central Portugal 1 / 185
Denmark 1 / 63
Finland 1 / 399
Gdansk, N. Poland 2 / 543
Groningen, N. Netherlands 1 / 48
Lousiana [Hispanic-American] 1 / 30
Munich, Bavaria 2 / 251
New York City [Hispanic-American]2 / 150
Northern Norway 2 / 45
Sweden 2 / 403
So Paulo, Brazil [Europeans]1 / 247
Uppsala, Sweden 1 / 55
Western Norway 1 / 64
I haven't looked at all n-step variations, (where n <=4),
but the ones I've seen are mostly northern European,
Iberian, South American, & some Hispanic-American.
What does FTDNA tell me? My exact 12 & 25 marker matches are with other "I"
people of northern European origin. 1-step mutations are in Denmark, Finland,
Greenland, Hungary, Iceland, Russia, Sweden.
2 steps to England, France, Italy... 3 steps to R1b, but the great
majority of all n-step mutations, n<=4, are all "I".
For migration paths I rely on the published papers and results of paper-trail
My Y-chromosome ancestors were American from 1640, English in England,
circa 1066 to 1640, Norman in France circa 800 AD onward, and before then,
probably Scandinavian, Saxon/Frankish. The DNA probably points to Danish,
rather than Norwegian, but there's just not enough data to be certain.
