basic information and explanation associated with the International Lindsay Surname
The first column, on the left of the table, is a Lindsay
Code Number that is simply an L# that was arbitrarily assigned
to each participant by the Project Coordinator to establish the
confidentiality of the DNA sample.
The second column is the Laboratory Case Number, assigned to this sample by the laboratory
upon receipt of the DNA sample.
The third column is the Surname column and is the actual
spelling of the Lindsay (how ever spelled) surname
of the participant.
The fourth column is the "inferred haplogroup"
that is predicted from the individual's marker alleles based on SNP testing
performed on others with similar allele values on several designated
markers. The nomenclature is derived from the 2008 version of the ISOGG SNP
The fifth column is the haplogroup information that has
been determined from actual SNP testing on the DNA of this specific
individual and represents the most "downstream" subclade SNP that
The DNA Group Number column provides a grouping of
participants based on a maximum of four (out of 43 markers), one-step DNA marker mismatches between
two or more participants.
The Test Round # column simply designates in which round of
testing this particular participant came into the database.
The next 26 columns, marked 1-26 near the top of the table, represent the
original 26 loci where the STR (Short Tandem Repeat) allele values were measured. The standardized
published DYS numbers and other nomenclature for a particular locus are also
Columns 27 through 45 represent the allele values for the
additional 17 markers associated with the 43-marker upgrade testing.
The last column is simply a duplication of the L# codes
placed on the right of the screen to help correlate the individual DNA
profiles from left to right.
For comparison purposes, the current
International Lindsay Surname DNA Project participants
been divided into categories (DNA Group 1 thru DNA Group 17) where appropriate,
with the balance of those participants who do not currently match at the end of
the table. These DNA Groups will contain all the participants who have matches which
indicate they likely have a Most Recent Common Ancestor (MRCA) within the
timeframe when surnames became common practice.
Each DNA Group will be composed of two or more people who have no more
than four (out of 43 markers), one-step, marker mismatches.
The "earliest known ancestor" will also
be provided for each of the participants in these seventeen (17) unique DNA Groups to
assist in developing the Most Recent Common Ancestor (MRCA) for each of these
groupings. The "earliest known ancestor" should not be confused
with the "earliest known proven ancestor". It is the
hopes of the Lindsay Surname DNA Project that one day soon our
participants will fully document their genealogies and we will be able to use
the "earliest known proven ancestor" term with confidence for all the
To really be meaningful, those participants in the
database who have not been grouped due to having more than four (4) mismatches
(out of 43 markers) with
the other participants will be required to wait until the International Lindsay Surname Haplotype
Database grows with the addition of more Lindsay males from which hopefully we
will find other Lindsay lineages that provides fewer
mismatches for their haplotype, yielding a potential common ancestor in the
* It has been established that the
use of the Lindsay surname, throughout this web site, implies all the accepted
different spellings of the surname found in the Orthography
section of this web site.
