HAM DNA Group # 7

  Y-SEARCH Study for the HAM Surname DNA Project

This Group has been tested as I1c  (also known as "I1b2a," and now known as I2b1 (I-M223) - but here the search was originally for "I1c." )

    GOAL:   To determine the possible ancestral origins for the HAM DNA Group # 7.

Date:      December  11,  2007

updated menu links and haplotype group name July. 2016, and updated links in May, 2018

Perform a Y-Search in order to determine the possible ancestral origins for the HAM DNA Group # 7.


        There have not been enough participants in Group #7 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 # 7" Haplotype:

The results:    Group # 7  Y-Search DNA Distribution (matches) throughout Europe

        Group #7 matches in England
        Group #7 matches in Ireland
        Group #7 matches in Scotland
        Group #7 matches in Germany

                                                                                                          Group 007


    To determine the possible ancestral origins for the HAM DNA Group # 7.


    5) Search the Y-Search database for matches to the ancestral haplotype.
         - From this search, report out the percentage matches that do NOT exist in the US.

These results could then be used to provide some guidance for locating ancestors in future research.

Step 1:

    Search the YSEARCH Database (www.ysearch.org) for matches to this "HAM DNA Group 7" Haplotype:

 85679     Stephen HAM
(1765 Culpeper Co. VA - 1821 Madison Co. KY)

    14    23    15    10    14    15    11    13    11    13    12    31    14    8    10    11    11    25    14    20    27    11    14    14    15

In effect, we are looking for the location to match this Group # 7 to the immigrant ancestor across the Atlantic.

Matching entered genetic markers on at least 12 markers, allowing a genetic distance of 1 per marker matched above 10.
Showing matches with Haplogroup I1c.  (This haplotype is also known as "I1b2a," but here the search is for "I1c." )
I am looking for about 1500 matches, in an effort to improve the statistics.  The search returned about 322 matches.

This Y-Search on the "Ancestral" Haplotype, and got a search that yielded 322 matches, using this search:


I then searched through these matches for all of the "known" and NON-USA matches, and tallied up the totals (186 were non-USA), then worked out percentages of where this "Ancestral" Haplotype should be found in the world.

The results:

Group #7 Ancestral DNA Distribution (matches) throughout Europe

322 matches obtained.
186 returned a Country other than the US or "unknown"


England:          48   +    United Kingdom:     8       56/186 =  30.1 %
Ireland:            36                                               36/186 =  19.4 %
Scotland:         30                                               30/186 =  16.1 %
Germany:        16                                               16/186 =    8.6 %
Switzerland:      7                                                 7/186 =    3.8 %
France:               6                                                 6/186 =    3.2 %
Denmark:           5                                                 5/186 =    2.7 %
Canada:             3                                                 3/186 =    1.6 %
Mexico:              3                                                 3/186 =    1.6 %
Netherlands:    3    (plus "Holland" = 4)        4/186 =    2.2 %
   Holland:            1
Sweden:           3                                                 3/186 =    1.6 %
Bahamas:         2                                                 2/186 =    1.1 %
Norway:            2                                                  2/186 =   1.1 %
Poland:             2                                                  2/186 =   1.1 %

OTHER (less than 0.5 % each):        6

Argentina          1                                                 1/186 =    0.5 %
Austria               1                                                 1/186 =    0.5 %
Brazil                 1                                                 1/186 =    0.5 %
Wales:               1                                                 1/186 =    0.5 %
Ukraine:            1
                                                 1/186 =    0.5 %
Russia:             1                                                 1/186 =    0.5 %

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 1.6 times as likely to be from England than from Ireland, and 1.87 times as likely to be from England than Scotland. And about 3.5 times as likely to be from England than from Germany.

Because I was observing the "I1c" haplotype, the Genetic Distance, was pretty much in line with what you might expect for a normal distribution.  It has occurred to me that the search may have to be repeated or corrected, since the numbers are so small.

At the moment, we have no participants in Group # 7 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 # 7 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 example.


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:

Staffordshire           (3)
  Kingstone, Staffordshire         1
  Stoke on Trent, Staffordshire  1
Bedfordshire           (2)
 Stanbridge, Bedfordshire       1
Middlesex               2

others (less than 4 each):            18

I might want to repeat here that this haplotype is also known as "I1b2a," but here the search is for "I1c."

It is apparent that from the locations in England, the most likely locations of origin should be closely matched by Staffordshire, followed next by  Bedfordshire and Middlesex

You can find a map of English Shires from the 10th century at:



From the results for Ireland, the obvious appears to be Northern Ireland.  County Cork and County Down having the largest totals.

The more significant totals as I have them:

Northern Ireland             (7)

County Derry      3
Dublin                2
Monaghan  (2)
   Rakeeragh, Ematris, County Monaghan   1
Tyrone       (2)
  Corderry, County Tyrone               1
   Killyman Parish, County Tyrone   1
Ulster               2

Notice that the total matching for County Derry match what we might expect from Staffordshire in England.


The more significant totals as I have them for Scotland:

Hazelbank         3
Argyll    (2)
  Morvern Parish , Argyll  1
  Ardfin, Jura, Argyllshire   1


Pfalz     (2)
Rheinland Pflatz                            1
   Roettersheim, Pfalz (Palatinate)   1
