This group has unique DNA and traces back to Bennington, South Lincolnshire. At present we believe this group are the Langtons of the Gilbertine Sempringham charters usually called Robert and William. The name comes from Lenton Lincolnshire formerly called West Langton.
We have two results from different groups who share a common ancestor born in the 1600s. One branch of the family is in Canada and the other in England. They have never met, or been in contact, but they share a very close DNA profile, being a 30/32 match with each other. There are only 2 mutations.
One mutation is at DYS 449, which is a rapidly moving marker. Andrew in England has 33 and David in Canada has 31.
The second mutation is at DYS GATA H4, which is a marker famous for different lab standards, so this may not be a difference at all. However if we assume the results are sound, Andrew in England has 11 and David in Canada has 12.
This goes to show how accurate these tests are, that two people who shared a common ancestor around 300 years ago, and who live in different parts of the world, match each other so closely.
R1b1a2 is the most common haplogroup is western europe, and in the UK makes up between 60 and 90 percent of the population, the larger amount occuring to the North West of Ireland and England.
King Tut is famous for belonging to this haplogroup.
It is worth pointing out however that this Langton profile, although belonging to the R1b1a2 haplogroup, is quite distinct. It has some very rare markers that differenciate it from the majority of other members of the haplogroup with other surnames.
In ten years time it will probably have its own officially designated branch with a much smaller percentage of members.
