To quote from familytreedna.com,
which did this testing:
Genetic Distance
When comparing people’s samples
in our system we show individuals who are closely matched, but
not identically matched, as being different by what the Anthropologists
call genetic distance.
If two people were identical in
all markers except they are off in one marker by 1 point, the
genetic distance would be 1. If they were off at 2 different
markers by 1 point in each marker, then the genetic distance
of those two samples would be 2. If they were off by 2 points
at one marker and 1 point in a second marker, then the genetic
distance would be 3. This is called the Stepwise Model of calculating
genetic distance for shallow time depths (i.e. Genealogy not
Anthropology).
If you and another person match
in all 12 loci -- If you share the same surname or variant, this
means that there is a 99% likelihood that you share a common
ancestor in a genealogical time frame. If you match another person
without the same surname or variant, you still probably share
a common ancestor, but this ancestor most likely lived in the
time before surnames were adopted.
It is obvious from our observation
of 10's of 1000's of samples that some markers change or mutate
at a faster rate than others. Therefore not all markers should
be treated the same for evaluation purposes.
The markers in
red have shown a faster mutation
rate then the average, and therefore these markers are very helpful
at splitting lineages into sub sets, or branches, within your
family tree.
Explained another way, if you match
exactly on all of the markers except for one or a few of the
markers we have determined mutate more quickly, then despite
the mutation this mismatch only slightly decreases the probability
of two people in your surname group who match 11/12 or even 23/25
of not sharing a recent common ancestor.

Alvis, John R., Chris,
and Paul Longley had a common ancestor probably 300-400 years
ago and belong to haplogroup R1b1.
They had a common ancestor
with Jay Longley (haplogroup R1b) probably 500-600 years ago
in England.

R1b1 Haplogroup is the most
common in European populations. It is believed to have expanded
throughout Europe as humans re-colonized after the last glacial
maximum 10-12 thousand years ago. This lineage is also the haplogroup
containing the Atlantic modal haplotype.
In the 1700s and 1800s, the family tradition of Benjamin Longley of Baltimore, Maryland, descendants was that their Longleys in Loudoun County, Virginia, were kin to ours who got there first, and used to visit back and forth. The two families, including William Longley, Revolutionary soldier, and his father Joseph Longley, moved from Hunterdon County, New Jersey, to Loudoun County, Virginia, in 1763-64 and some still lived there when Benjamin's children came to Loudoun County and after a few years moved back to Baltimore or to Ohio or Tennessee or further south in Virginia.
Their suspected kinship was proven by exactly matching Y-chromosome DNA of a descendant in Texas and one in Minnesota, followed by two other known descendants of William Longley. Others need to be tested to corroborate the evidence.
Next, three men named Langley were tested, whose ancestor Moses Langley of South Carolina moved to Missouri, with results matching the Longleys on the first 12 markers of the test; however, results on markers 13-25 or 13-27 lost the correlation. Moses lived among and is thought to be related to the Langleys descending from William Langley in Lower Norfolk Co., VA, before 1653.
Currently 11 Longley or Langleys have been tested in the Longley DNA Project; two are one genetic distance from the others, so have a common ancestor a bit further back; and two do not show a common ancestor. Another 400+ subjects of other surnames tested by familytreedna match our family on 12 of 12 markers but do NOT have the Longley/Langley surname.
This means their common ancestor was BEFORE surnames were adopted, which began after the Norman invasion of 1066 introduced surnames to England -- a very gradual process.
Although three men named Langley participate in the Longley DNA Project and match the Longleys, they do NOT match any of the 39 test subjects in the separate Langley DNA Project.
The other matching test subjects' surnames range from A to Y, including Alford, Allen, Broom/Broome, Cassidy/Cassity, Collins, Davis, Elliott/Elliston, Fox, Gmuer/Gmur, Gordon, Gray, Hatton, Ervin/Irvin/Irvine/Irving/Irwin, Maines/Manes, Mauck/Mauk/Mock, Montanez/Montez, Peters, Porter/Potter, Reed/Reid, Robinson, Smith, Stewart, Strickland, Walker, Williams, Wilson, and many others from many countries (United States, Scotland, Ireland, Australia, New Zealand, Spain). The relatively small portion who submitted their pedigrees list their ancestral origin as England or several of its counties, Scotland, Ireland, many as Unknown.
Origins
The earliest Langley record found thus far in Virginia was in 1622 when William Langley gave a deposition in a case involving the owners of ship Falcon. This was prior to creation of the eight shires in Virginia and the town court was probably London, but relating to Virginia.
Someone said, "I believe all the Longleys descend from one man in England," but that's very unlikely. Langley/Longley was a place name, and the one Longley wealthy enough to be listed as a landowner in the 1086 Domesday Book probably had descendants, he would have had surfs who assumed his surname as that practice began to be adopted from the Norman after their invasion in 1066. While many Langleys/Longleys no doubt descend from that one prominent man, many others do not, judging from Y-chrome DNA analysis. Langley is the more common spelling. Early records of our family had both spellings, Langley and Longley, until it became fixed as Longley in 18th century Virginia and Maryland.
The Langley site has a very interesting discussion of the origins and English locales of the surname. Langley Project Test Results.
