Note: Samples marked FT followed by a 5 digit number were taken from the McLaughlin surname project on FamilyTree DNA.
Samples marked SMGF were taken from the Sorenson Molecular Genealogy Database.
Samples were truncated to 25 markers for ease of presentation.
It now appears that the MacLochlainn of Tirconnell sept in Ireland originating in Derry and the Foyle shore of Inishowen
match the NW Irish or Ui Neill modal perfectly.  A core group of McLaughlins with verifed origins in Donegal and Tryone
all match the Ui Neill modal.  A second larger group with less certain origins also match the core group, characterized by
a value of 18 at DYS 458.  Other McLaughlins have a value of 17 at the same marker.  We do not yet know if this value
is showing branches of the McLaughlin of Tirconnell sept or a different McLaughlin sept from elsewhere in Ireland or Scotland.
We also have a fairly large group of non-matching McLaughlins who are not Ui Neill.  Their stated origins are so imprecise
it is impossible to say anything about them at this time.
McLaughlin DNA Project
There is a McLaughlin surname project listed on the FTDNA site.
Family Tree DNA
The group rate for this project is $189 for a 37 marker test. A 25 marker test is $148 (U.S.). 12 marker tests are not adviseable.
The McLaughlin Surname Project on FTDNA has some surnames that overlap with entries on Ysearch. An attempt at correlating names has been made to try and avoid duplicate listings. The Ysearch user codes have been used wherever possible rather than the McLaughlin Surname project codes. Blank listings under the surname are assumed to be McLaughlins or a variant form.
