DNA Results for Rowden

Introduction
The use of DNA testing for genealogical matching comprises the checking for certain markers in the DNA or 'genetic make up' of an individual. For each marker tested a numeric allele value is calculated as a measure of the pattern at that particular place in the DNA. The results from a set of markers may be considered like a genetic signature.

When the genetic signatures of two of more individuals with identical or similarly spelled surnames match, then it can be assumed that they share a common ancestor within a recent number of generations. The closeness of the match will depend on the number of markers used in the test and the degree of agreement between the results. The numbers of markers tested is typically 12, 25, 37 or 67 depending of the degree of matching desired. The difference between each of the marker values for any two individuals may be summed to generate a 'genetic distance'. A more complete description may be found at the FTDNA website.

Y-DNA Results
The results of those already tested within the Rowden project are shown in the table below. These are grouped into similar genetic profiles irrespective of apparent geographic origin. Genetic distance from the first entry of each group is indicated in the last column. Greyed cells highlight marker values which differ from the modal profile. Note that the sept of each project member is now shown.

The results are mostly from Rowdens in different septs.

Group A Results
In group A the results of the first two individuals show an exact match on all 37 markers (genetic distance of zero) indicating that they have a common male ancestor in recent generations. The last three individuals have just one marker with a difference of one unit from the preceeding two. There is a 99% probability that the common ancestor of all individuals in these septs lived within the last 10 generations, in the time of the 17th century. Although the families of these fives males all originate in Devon, they currently appear in four separate septs. The next task will be to find the paper trail evidence for their common parent.

Group B Result
When comparing the results of group B with group A a significant difference is noted. This would seem to indicate that although the groups have the same county of origin, there may be a second family origin in Devon.

Group C Results
The results of group C are particularly interesting. They show four almost identical profiles of Rowdens from geographically different counties in England, namely Herefordshire, Kent and Wiltshire. The results of the two Kent Rowdens are so close, giving us reliable genetic signature for this family. It has long been my theory that the Rowdens in Kent have their origins in Wiltshire and the evidence of another close match to a Wiltshire Rowden supports that proposition.
One of the oldest Rowden families traces its roots to the 14 century in Herefordshire so these 4 results have the potential to draw a number of families together. If you are a Rowden one of these counties, please add to the evidence and use the link below to joining the project and take a test.

Group D Result
With a family origin in Wiltshire this result was expected to have a link with group C but there is a striking difference when comparing the genetic signature with those from that group. This could point to another ancestral origin in Wiltshire.

It will also be seen that the profiles of the Rowdens from Devon and Wiltshire are significantly different. This indicates that the two families are very unlikely to have had a common ancestor. It may be deduced that the two families received their surname from a topographical context, based on where they lived. See 'What's in a Name' For more information.
