This profile group belongs to the haplogroup I2a1.
We have been able to prove that Stephen Langton of Cheshire, and Paul Langton of Manchester, are related. Their family branches having diverged approximately 300 years ago - which resulted in one mutation at marker DYS462. The other interesting thing about this family is that for several generations they were recorded erroneously as Leightons, although this mispelling never stuck.
Stephen Langton's family down in Cheshire, seem to have come from Lancashire originally, and have specific links to the area where the Langtons were Lords of the estates of Walton-le dale near Preston, England and Newton-le-willows near Wigan, England.
This family originally came from the Langton villages in Leicestershire and moved to Lancashire in the 13th century. It seems therefore that this profile group have their origins in Leicestershire at one of the cluster of Langton villages (West, East, Tur, Church, Thorp). It was probably West Langton, as records suggest that the early Lancashire family held some lands still in West Langton. This would have been the original Langton family from West Langton. There is a second Langton family from West Langton, the descendants of Bishop Walter Langton of Lichfield, who we have been able to show have different DNA to the original family. This actually makes sense as Walter Langton is recorded as saying that his father was Peverell, not Langton. Langton was probably his mothers name, and his adoption of the name was probably tactical. One reason to adopt the name was that there had been famous Langtons holding office in the church - i.e. Stephen, the archbishop, his brother Simon, the Archbishop of York (elect) and their descendant, a contempory of Walter, John Langton the Bishop of Chichester. None of these Langtons were related to Walter, or even came from Leicestershire, but that doesnt mean Walter couldnt still suggest a connection.
The West Langton, Leicestershire group fits within the M26+ subclade called I2a1a at ISOGG and "I2a1" at places like FTDNA that still don't recognize L460
So what about Thomas Joseph Langton and Bryan Langton?
You will notice that Thomas Joseph Langton's DNA profile does not match, it comes from a distinctly different haplogroup. But, still, he is a Langton and the family traced back to the same area of Lancashire, around Chorley. So when this result came through, everyone involved did some research to find out what had happened, and if the two different profiles came from different Langton origins, or else were related somehow.
The result was that Thomas Joseph Langtons ancestors do trace back to the same family, but specifically, back to a join where a known non-paternal event occured with the child being fathered by a Richard Hough. We then checked what matches his DNA showed up on Y-search (the free online database of Y-STR results) and he matches one person with the name Hough. Thats a pretty fantastic result.
There are anomalies (a=anomoly in the main DNA Project table) in the DNA profile of Bryan Langton. His family trees intersects with the others grouped immediately above him in the tree, however his paternal DNA is different from the rest of the group.
