STUDY TO REVEAL WHICH BARLING BRANCHES ARE LINKED AND THEIR ORIGINS
Results as of March 2011:
The DNA Results Comparison Table shows the raw DNA results for each of the 9 BARLING men tested so far. For each DNA Marker (e.g DYS393) a Value was measured and these are listed in the table. NOTE: There are gaps, as not all Markers were tested for each sample.
Differences in the Values for each Marker, relative to that of "Jim", are highlighted in colour:
The Time to the Most Recent Common Ancestor (TMRCA) Table gives a comparison between any pair of testers. The Table displays the TMRCA in years. TMRCA is an estimate, based on probability, of when the most recent strict male-line ancestor who was common to both testers might have lived. As an example, the common ancestor of Jim and John is predicted to have lived about 150 years ago, and that of Jim and Chris about 300 years ago.
NOTE: The diagonal shows the number of MARKERS used for each tester; The larger the number the greater the predictive confidence.
Testers, their origins & interpretation
Jim. Romsey Branch. Descendant of Moses BARLING
John. Romsey Branch. Descendant of George & Eliza BARLING
Chris. Romsey Branch. Descendant of James & Edith Louisa BARLING
Col. Romsey Branch. Descendant of James & Edith Louisa BARLING
Harold. Egerton Branch. Descendant of BARLINGs of Lynsted
Kenneth. Egerton Branch. Descendant of BARLINGs of Lynsted
Lloyd. Kingston Branch. Descendant of BARLINGs of Kingston
Pat. Warehorne Branch. Descendant of BARLINGs of Warehorne
Don. Brookland Branch. Descendant of BARLINGs of Brookland
Jim, John, Chris & Col share a common ancestor in John BARLING married 1682 in Hampshire
Harold & Kenneth share a common ancestor in Philip Charles BARLING born 1868 in Doddington, Kent
Lloyd, Pat & Don represents three other lines. That of Don is believed to be the same line as that of Harold & Kenneth.
The DNA results show that Testers Jim, John, Chris & Col are indeed descendants of a common ancestor. Their DNA markers are very similar, though there are significant differences (see below). These are consistent with the common ancestor having lived about 300-500 years ago.
The DNA results for Testers Harold & Kenneth are as expected very similar to each other as they are closely related. However, they differ significantly from Testers Jim, John, Chris & Col and the other 3 Testers, including Don. It is most likely that the common (strict male-line) ancestors lived more than 1500 years ago.
These data suggest that the "Romsey" Barlings may not share a recent common origin with other Barling lines. This can be made more certain if other members of the Barling families from Egerton and other places in Kent offer to participate in this project.
The results of Lloyd, Pat and Don suggest that they only share common male-line ancestors long before the surname BARLING would have originated. The same applies in comparison with the top 6 testers in the Table. Taking the results at face value one could conclude that the Kingston, Brookland, Warehorne, Romsey, and Egerton Barlings do NOT share a common ancestral BARLING. In one case, this disagrees with the genealogical data that shows that the Egerton & Brookland branches are indeed a single line.
The DNA analysis is based on the assumption that the genetic (biological) male-line is identical to that of the genealogical line, and that no "non-paternity events" have ever occurred in any of these lines. Statistically, it is likely that in fact some of the DNA data will be misleading because this assumption is not met. To reduce the likelihood of being mislead, it can be necessary to test two BARLING men from the same branch, but related as distantly as possible.
For the Romsey Branch this has been done, and the changes in Marker values can be mapped nicely onto a genealogical tree:
The project is still at an early stage. However, it is clear that these simple DNA tests can be used to determine which BARLING branches share a common ancestor, and to distinguish sub-branches. This can be used to confirm previous genealogies or to establish new connections. MORE BARLING MEN ARE REQUIRED AS VOLUNTEERS !!
