Mapping Viking Migration with Y-DNA STR's



Mapping Viking Migration with Y-DNA STR's


Y-DNA analysis of STR information can provide clues to Viking migration in recent time frames. The Y-DNA STR YMRCA estimates suggests that the Norse (Vikings) could have originated from seafaring peoples of the Mediterranean Sea.











In March, 2011, the results of grouping the DNA STR information by country for the I1 (M253) haplotype were studied.

These results suggested a migration along a sea-faring route in recent time frames. In order to visualize that, a possible migration route is presented here. As stated in the article in March, the method does have some problems. It may be worthwhile to visualization the difference in from currently posted maps of SNP's in order to contrast with what was found from the STR study.

Most SNP maps today show an overland route for M253 either through the mountains of Europe, or through the general vicinity of Germany. The STR map (below) suggests a sea-faring route, based upon TMRCA estimates for STR modal groups by country.

Revolutionary War Quick Studies


Revolutionary War
Quick Studies




Drury Ham has to be my favorite HAM Revolutionary War Veteran. His account of his activities as an Indian Spy, combined with his recollection of the Battle of Cowpens is fairly colorful material. Mordecai Ham was a dragoon at the Battle of Guilford Courthouse. William Ham was at the Siege of Yorktown.











If you are looking for a quick study regarding the battles of the Revolutionary War, Jeff Weaver has a few small (and inexpensive) books listed on his Lulu web site. These brief books would be a good companion to our history. These books (below) generally have a good overview of the action, maps, graphics, and an index. These battles are considered to mark the point where the Americans began to win the Revolutionary War.

In our book "A Short History of the HAM Surname in Virginia & NC," we list some details about the Revolutionary War veterans that carried the HAM(M) surname. There were HAM(M) Revolutionary War Veterans that fought in each of the battles that are considered to have turned the tide of the war. Jeff Weaver's books should be of interest to those who want a brief overview (50+ pages) of these battles.

There were Ham(m)'s who were Revolutionary War Veterans from each of these battles:

Battle of Kings Mountain
Battle of Cowpens
Battle of Guilford Courthouse
Siege at Yorktown



Battle of Kings Mountain         (October 7th, 1780  Near Blackburn, SC and King's Mountain, NC)



During the summer of 1780, British commander Patrick Ferguson travelled through South Carolina into North Carolina  gathering loyalist support for the British. After a string of small battles (Wofford's Iron Works, Musgrove's Mill, Thicketty Fort, and Cedar Spring) the campaign culminated in August with the defeat of the Americans at the Battle of Camden. The American "Over Mountain Men" retired to their homes in North Carolina to rest.

In September, British General Cornwallis ordered commander Ferguson to the north, before joining the main British forces again at a later time. By October 7, Ferguson had camped at King's Mountain.

American Colonels McDowell, Sevier, Shelby and Campbell gathered in Tennessee and marched to (present day) Morganton, joining those serving under Cleveland and Winston. On October 6th, they joined forces with Colonel Williams at Cowpens.

The American soldiers marched through the night and arrived at King's Mountain on October 7th. They surrounded the mountain in a horshoe formation, taking cover in the heavily wooded area. The battle lasted about an hour and 225 Loyalists were killed, 716 were taken prisoner. 28 Patriots were killed.





Battle of Cowpens                  (January 17, 1781  Cowpens, South Carolina)





Maj. General Nathanael Greene needed time to recover from the Battle of King's Mountain, and split his mobile force off to be under the command of Brig. General Daniel Morgan. The British Lt. General Charles Cornwallis recognized the strategy and sent his own mobile force under Lt. Colonel Banastre Tarleton after Morgan. After several weeks of maneuvering, General Morgan finally had to choose his ground before Lt. Colonel Tarleton overran him.

Morgan settled on Cowpens, South Carolina. Morgan's strategy was that the British would expect a retreat. Part of Morgan's plan was for Andrew Pickens' militia to feignt a withdraw by firing three times, and then falling back. When the battle took place, the British became undisciplined and broke ranks in pursuit. This loss of discipline allowed the planned actions of the Continentals to thoroughly rout the British and destroy General Cornwallis' light troops.




Battle of Guilford Courthouse   (March 15, 1781  Greensboro,NC)



After Cowpens, the British General Cornwallis pursued the American General Nathanael Greene to Guilford Courthouse, North Carolina. By this time Greene had built a substantial force (mostly farmers who were nonprofessional temporary soldiers of short duration).

On March 15, General Greene deployed his men in three lines of battle across the Great Salisbury Wagon Road that led off to the southwest toward the camp of the British army. The front line was deployed against a rail fence that surround farm fields and extended into the forest. The second line was located within the forest behind the first line.

The British Highland Regiment attacked, and suffered heavy losses before breaking through the center of Greene's front line. The second line fought for about an hour and was broken by the British, but only after the British again suffered heavy losses. The heaviest fighting was at the third line, where the British General Cornwallis found his men being attacked from the remaining two sides of American forces. The battle culminated when Cornwallis decided to fire his cannon into the center of the struggle, killing his own soldiers in the process. When the smoke cleared, the American General Greene ordered a retreat. Cornwallis had won the battle, but suffered heavy casualties.



From King's Mountain to Yorktown

 (Siege at Yorktown   October 09, 1781  Yorktown, Virginia)



By midsummer, 1781, the Continentals under General Nathaniel Greene had gained virtual control of South Carolina. By September, 1781 Greene had an apparent loss at the Battle of Eutaw Springs to British commanders Arbuthnot and Stewart. Nevertheless, Greene put an end to British conquests in the south.

Also that month, French commander deGrasse defeated a British Fleet that had come to relieve Cornwallis (Battle of the Chesapeake). As a result of this victory, de Grasse blocked any escape by sea for Cornwallis. British General Cornwallis was stationed in Yorktown, Virginia and was surrounded by land and by sea when George Washington arrives. Trees were cleared, trenches were dug, and redoubts were taken. By October 9th, Rochambeau's French cannons would begin the bombardment.

Ancient Migrations Using STR TMRCA

Ancient Migrations

An analysis of time frames using Y-DNA STR TMRCA estimations










It may be useful for family historians to use Y-Search data in order to understand ancient migration patterns for their family line.




A number of folks disregard the results from Y-Search that do not provide a DNA match beyond a Genetic Distance of 6. That's because most are only interested in genealogical time frames. Deep ancestry is usually left to obscure SNP notations that may or may not make sense to the average genealogist. The general migration path for an SNP can trace out a migration path dating to tens of thousands of years ago.


However, a family historian might be just as interested in what happened within the last two thousand years, in the hope that some day, supporting documentation may be found, or at least put on their search list.



If you have an idea of where your line originated from within the last two thousand years, then you have an idea of whether or not you should be interested in, for example, Normans. Or Saxons. Or Romans.
I had not completed my migration study of HAM DNA Group #1 when I posted the article (about being in a line from England that also matches Y-DNA for Norway and France. http://hamcountry-blog.blogspot.com/2011/05/england-traces-in-france.html - see cluster #2). However, from the chart listed there, I could have just as easily listed out the data in chronological order, such as:


present............U.S.

1577 AD........Virginia
1288 AD........County Somerset, England
913 AD........Broennoeysund, Norway

855 AD........Gloucester or London, England

638 AD........Dirksland or Margraten, Netherlands

465 AD........France

335 AD........Devonshire, England


Which should represent a broad outline of the migration of my own line (HAM DNA Group #1). Not a whole lot of movement there, apparently a fairly stable group. And, my analysis was not really completed (not all of the data was analyzed). The curious entry there (for my group) would be to determine where the group from Devonshire was at 335 AD.


The basic idea is to create the phylogram from the Y-Search data such that you know where the other Y-Search kits may have branched off. Then use Dean McGee's Utility to find the TMRCA in order to estimate an approximate timeline for the migration of your family group.

Without getting into very much detail, I have done this for another I1 haplotype group (WIDEBURG surname). For this study, the Y-Search data was divided into small groups, then Dean McGee's utility was run to get the TMRCA's, and the phylograms were run on the groups in order to determine what was branching off and what was not.


The Wideburg results resembled a migration pattern such as this:

Wideburg............ now.........Sweden

England16........ 1505.........Harpole, Northampton, England; London, England; Thurlby, England

England15........ 1580.........Norwich, England

Ireland19........... 1430.........County Kerry, Ireland

Germany24....... 1305.........Cabell County, Germany

Netherlands07.. 1305.........Netherlands

Denmark03....... 1230.........Stadil, Denmark

Germany08....... 1155.........Germany

England01......... 1080.........Essex, England

England04......... 1030.........Benwick, Cambs, England; Moulton, Northampton, England; Essex, England;

...............................................Newbold Verdon, England; Liverpool, England; London, England;

...............................................Bristol, Gloucestershire, England
Scotland06.........1030.........Renfrew (Port Glasgow or Paisley), Scotland; Pike County, Georgia, Scotland

France01............1030.........Tonquédec, France; Oberroedern, Alsace/Elsass, France

Denmark05..........805.........Laurbjerg, Denmark

Germany38..........730.........Germany

Germany50..........730.........Oberstenfeld, Germany

France03..............655.........France

Germany45..........580.........Falkenhagen, Pomerania/Pommern, Germany

Slovenia02...........500.........Gradenc, Slovenia

Switzerland11......405.........Buettenhardt, Schaffhausen, Switzerland

Sweden05...........155..AD.........Lindesburg Parish, Sweden

Which suggests an I1 migration pattern perhaps originating from Slovenia, and perhaps migrating through Germany via the Danube, through Denmark, France, Scotland, and finally arriving in England, then Sweden. A lot of movement for this group, and the analysis was done by placing similar kits within each country into small groups. The curious point here being to try to understand where the Switzerland group actually was located in 405 AD, as well as the location of the Sweden group in 155 AD.

However, the interesting point for the Wideburg surname is that they are found in Denmark at about the time of the Danish Vikings, and are found in France and England at about the time of the Norman invasion.
However, dividing kits matched by country is no guarantee that you will see movement as clearly defined. When the study was run on the STANLEY surname, the results appeared to be  unreliable for placement on the phylogenetic tree prior to 700 AD. The migration path for this R1b group traced out like this:



STANLEY..... ARJYZ .........Now


England046...........1360.....AD........GBWJC......Salkeld........Salkeld Parva, Cumberland, England
Scotlan033............1216.5..AD........GSMDW....Guthery.........Scotland
Germany017...........953.5..AD........4MRWP.......Harmon.......Woerttemberg/Wurttemberg, Germany
England096.............910.8..AD........83Y4V.........Curtis...........West Farmington, England
Sweden03...............836.0..AD........SKNTC.......Johansson...Jonsberg, Ostergotland, Sweden
Scotlan034..............727.4..AD........N9SQE.......Downie.........Lanarkshire, Scotland
Sweden07................684..AD........NHVM    Anderson   Goteborg, Goeteborg & Bohus, Sweden
France08..................598 ..AD........JQXXQ     Fousse     Alsace-Lorraine/Elsass-Lothringen, France

Scotlan032 ...............440..AD........Scotland
Sweden06 ...............408 ..AD........Nordmaling, V???sterbotten, Sweden  (Visigoths under Alaric sack Rome in 410.)
Norway03 ................398 ..AD........Mandal, Norway
Germany019..............391..AD........Roethenbach an der Pegnitz, Bavaria/Bayern, Germany (Visigoths defeat the Romans at the Battle of Adrianople in 388)
England097..............346 ..AD........Hertfordshire, England
Germany021..............344..AD........Rheinland-Pfalz/Rhineland-Palatinate, Germany
Germany027..............316..AD........Wurzburg, Germany           (Wurzburg is, perhaps, 150 miles from Trier.)
Germany024..............306 ..AD........Germany   (307 Emperor Constantine is in Britain, and sends troops against Germanic tribes along the Rhine, begins a major expansion of Trier.)
England100..............303 ..AD........Plymouth, Devon or Devonshire, England
England103..............285..AD........Baldwin, Isle of Man, United Kingdom
England098..............285 ..AD........Chorley, England    (Roman Carausius, is put in charge of operations against Saxon and Frankish pirates on the Saxon Shore.)
Italy07  ......................196..AD........Mezzojuso, Italy      (Roman Battle of Lugdunum was fought in 197 AD)
Germany026..............180 ..AD........Schnait im Remstal, Wuerttemberg, Germany  (Roman Praetorian Prefect Teratenius Paternus defeats the Quadi.)
England106 ..............168..AD........Corby, Northamptonshire, England      (The Marcomannic Wars ca 166 - 180)
Germany028..............151..AD........Friedrichroda, Germany
England108 ..............133 ..AD........England              (Antonine begins construction on his wall in 142 AD)
England110.................80..AD........England              (Hadrian begins construction on his wall in 122 AD)
Germany029...............59 ..AD........Hofheim, Bergstrasse, Hessen, Germany (Gnaeus Domitius Corbulo captures Tigranocerta)
Netherla05..................57..AD........Domburg, Zeeland, Netherlands
Australia3...................23 ..AD........Australia             (Australia isn't settled by Europeans until about 1600)
Germany031................8..AD........Wittenberg, Germany (Roman Battle of the Teutoburg Forest)
France09 ....................3  BC..........Bourges, France   [Caesar conquers Bourges (Avaricum) ca 50 BC]


Looks like the last 1,000 years have mostly been in England and Scotland. Prior to that they have a German element, with some indication of the possibility of some ties to Italy and Sicily. So, it looks like that STANLEY line may be Anglo Saxon, with something that looks "Romanesque."


The timeline for the period from 0 AD to 700 AD was updated on Nov 27. 2011, but the phylogeny did not appear to be stable. That is, it is likely that the timeline would may be correct (mostly due to the number of markers tested per kit for the period). The original article only listed the results back to 727 AD. Historical references for the date and location were taken from Wikipedia.


The oldest STR match found indicating possible origins in France.

For the Stanley surname, the Y-Search results had been divided into some 158 groups, mostly 67 markers with less than 20 kits that had been tested to 95 markers. Most of these beyond 67 markers were panel upgrades, which caused a little bit of manual effort to sort in correct order.


The dates do not really provide an explanation of the reasons for migration. It might be reasonable to expect that short periods of migration along coastal areas or waterways to be trading activity. But, it might be difficult to interpret the difference between trading activity and military operations. More information with regard to historical references may help in the interpretation of the activities during the time periods.
