GOAL: To determine the possible ancestral origins for the HAM DNA Group # 4.

GOAL:Perform a Y-Search in order to determine the possible ancestral origins for the HAM DNA Group # 4. PROCEDURE
There have not been enough
participants in Group #4 for an Ancestral procedure, so a simple
Y-Search study has been performed here.
Step 1:Search the Y-SEARCH Database (www.ysearch.org) for matches to this "HAM DNA AGroup # 4" Haplotype: The results:
Group #4 Y-Search DNA Distribution (matches) throughout Europe
In effect, we are looking for the location to match this Group # 4 to the immigrant ancestor across the Atlantic.
Matching entered genetic markers on at least 15 markers, allowing
a genetic distance of 1 per marker matched above 10.
I am looking for about 1500 matches, in an effort to improve the statistics. The search returned about 1000 matches.
This Y-Search on the "Ancestral" Haplotype, and got a search
that yielded 1025 matches, using this search:
I then searched through these matches for all of the "known" and NON-USA
matches, and tallied up the totals (494 were non-USA), then worked out
percentages of where this "Ancestral" Haplotype should be found in the
Group #4 Ancestral DNA Distribution (matches) throughout Europe
1025 matches obtained.
494 returned a Country other than the US or "unknown"
Belarus 1 Czech 1 Israel 1 Russia 1 Serbia 1 Sicily 1 Sweden 1 Turkey 1
Presuming that we
could determine something from these totals, I would guess that this
group should be found mostly in England, with smaller portions from
Ireland and Scotland. It would appear that they should be twice as
likely to be from England than from either Ireland or Scotland, and
over 4 times as likely to be from England than from Germany.
The problem that I
am observing is the Genetic Distance, which appears to be larger than I
would have wanted it to be. (Given the current search options from YSearch, I did not permit more than one mutation
per marker, in an attempt to obtain some meaningful results. ) It
has occurred to me that the search may have to be repeated or corrected.
Therefore, I did
repeat the search (original search was in January, 2007) with a return
of 1916 matches, which gave about the same percentages. However, the
January search was of lower quality, only searching for matches on 8
markers. Although the general percentages remained the same, but the
specific percentages changed somewhat (for specific locations).
Today, the Y-Search database is reflecting improved data from an
increase in the number of participants.
Very similar results as Group #2 ( R1b1c ), until the list falls below England, Ireland, Scotland, and Germany. At the moment, we
have no participants in Group 4 that can indicate the immigrant
ancestor with any certainty, but he is presumed to have immigrated from
England, since Virginia was a colony of England.
More differences from Group #4 appear when the distribution is listed within each country (below).
It is interesting that for these countries, many give city or county
locations. It is almost as if I could see how many locations are in
common for the majority matching in England, Ireland, or Scotland, for
From the totals
that I have for England, and without going to very much trouble of
attempting to determine the name of the County for the cities, I get a
rough account of the results that look something like this:
County Worcester (or Worcestershire) 12 (Not applicable, as all from Worcestershire indicated haplotype R1b1c, as opposed to I1b.) Kent
7 London 5 Yorkshire 4 Cornwall 4
others (less than 4 each): 18
Of those that matched Worcestershire, these were matches to the R1b1c haplotype, similar to our HAM DNA Group # 2. The HAM DNA Group # 4 here is tested out as I1b.
So, I did not exclude other indicated haplotypes (R1a, R1b3, etc.) from
this particular search. This indicates to me that this search
will need to be refreshed as the data becomes available.
that from the locations in England, the most likely locations of origin
should be closely matched by Kent, followed next by Suffolk,
London, Yorkshire, Cornwall, and so on. Group #4 appears to
be distributed widely in England among at least the top 5
