Addington Family DNA project

 sponsored by the Addington Association and coordinated by Dr. David V. Addington

There are four major Addington families in the USA and to date genealogical researchers have not been able to connect them with any vital records.  The purpose of this study is to use advances in genetic technology to see if these families are closely related.  Eight DNA samples were gathered from male descendants of 5 Addington families and compared.  These are the results of this study. 
I hope you find it interesting.

D V Addington is a 7th generation descendant of Henry Addington of South Carolina thru son John

A Addington is a 7th generation descendant of Henry Addington of South Carolina thru son James

C P Addington is a 7th generation descendant of Henry Addington of South Carolina thru son William

They match 25 for 25 in the Y DNA25 test.  At a common ancestor 7 generations back,  this is the expected match.

Using the standard mutation rate, the number of generations to a Most Common Ancestor is

B Addington is a 7th generation descendant of John Addington of Connecticut born about 1719

This Y DNA matches 24 of 25 sites in the Y DNA25 test with a one step mis-match at site 13 to the above results

Using the high mutation rate, the number of generations to a Most Common Ancestor is

Interpretation:   Henry Addington of SC and John Addington of CT are probably related another 3 to 7 generations back

N Addington is a 6th generation descendant of William Addington (1750-1807) of Virginia thru his son Charles Cromwell and his grandson William

D Addington is a 7th generation descendant of William Addington (1750-1807) of Virginia

Their DNA matches exactly at the first 25 markers as would be expected for a common ancestor 6 or 7 generations back.

Their Y-DNA matches 7 of the first 12 sites, and 14 of the 25 sites with the first group of samples above.  The Haplogroups are both E3b.

Interpretation:   Henry Addington of PA and SC and William Addington of VA are not closely related even though they carry the same family surname

P Addington is a 5th generation descendant of Henry Addington (1774, MD -1850, KY) of Ohio Co., KY thru his son William Blackman Addington.

This Y-DNA matches only 5 of the first 12 sites for the first set of data (Henry of PA and SC), and 10 of the first 25 sites.   This Y-DNA matches only 4 of the first 12 sites for the second set of data (William of VA) and 10 of the first 25 sites.  The Haplogroup is initially listed as R1b1 and different than the above samples.

Interpretation:   Henry Addington of MD/KY is not closely related to either Henry Addington of PA/SC or William Addington of VA.

H Addington is a 5th generation descendant of Sabird Addington (b. 1804, NC) who first shows up in TN in 1833.  It has been thought by several researchers that Sabird Addington was probably related to Henry Addington of SC because of the date and location of his birth.

This Y-DNA matches only 3 of the first 12 sites for the first set of data (Henry of PA and SC), and the Haplogroup is initially listed as R1b1.  This Y profile does not match any of the other Addington families either.

Interpretation:   The Addington family starting with Sabird Addington, b. 1804, NC,  is not related to any of the Addington families above.

SUMMARY

The Addington family of Henry Addington of PA/SC is closely related to the Addington family of John Addington of CT.

The other 3 Addington families (William Addington of VA, Henry Addington of MD/KY and Sabird Addington, b. 1804 NC) are not related to each other or the Addington family above.

Even though each family carries the Addington surname, they must have picked up the name in different locations or under different circumstances.

Before this study, there were some family stories about lost brothers, etc but no firm evidence of how these 4 Addington families  (Henry of PA and SC, John of CT, William of VA and Henry of MD/Ohio Co., KY) were related.  This y-DNA study shows that Henry of PA and John of CT are closely related, somewhere back in England.  These 3 other Addington families are not closely related to this Addington family.  This is new and significant information to the genealogy enthusiast.

Where do we go from here?  The biggest question remaining for each of the above groups is from where in England did they come.  If we could identify Addington males in England who can trace their Addington ancestry to specific ancestors or locations, then y-DNA matches with them would give us an ancestor or English location from which to do further searching and research. 

The e3b Haplogroup is not the most common haplogroup in Great Britain and is seen at a concentration of 1 to 6% in the central shires.  It is thought to have been brought to Great Britain by the Romans times or perhaps earlier than that.  It probably came up from the Iberian Peninsula.

In two recently published books, Blood of the Isles, by Bryan Sykes and The Origins of the British, by Stephen Oppenheimer, both authors state that according to genetic studies (mainly Haplogroup R1b as well as E3b, I, J (Y-DNA) and Mtdna), most Britons descend mainly from ancient populations of the Iberian Peninsula, as a result of different migrations that took place during the Mesolithic and the Neolithic, which laid the foundations for the present-day populations in the British Isles, indicating an ancient relationship among the populations of Atlantic Europe. Both Authors claim that there is evidence for this on both the y-chromosomes and maternal dna. Stephen Oppenheimer is even able to date when migrations to the British Isles took place and where exactly within the Iberian peninsula these different migrations originated. Stephen Oppenheimer also claims that there were neolithic invasions to Scotland from Norway prior to Norwegien Viking invasions and that the Vikings would take the same invasion routes as their previous neolithic invaders.[10][11][12]

In Origins of the British (2006), Stephen Oppenheimer states (pages 375 and 378):

By far the majority of male gene types in the British Isles derive from Iberia (Spain and Portugal), ranging from a low of 59% in Fakenham, Norfolk to highs of 96% in Llangefni, north Wales and 93% Castlerea, Ireland. On average only 30% of gene types in England derive from north-west Europe. Even without dating the earlier waves of north-west European immigration, this invalidates the Anglo-Saxon wipeout theory…
…75-95% of British Isles (genetic) matches derive from Iberia...Ireland, coastal Wales, and central and west-coast Scotland are almost entirely made up from Iberian founders, while the rest of the non-English parts of the British Isles have similarly high rates. England has rather lower rates of Iberian types with marked heterogeneity, but no English sample has less than 58% of Iberian samples…
In page 367 he also states in relation to Rossers's pan-European genetic distance map:
