International Lindsay* Surname DNA Project

Introduction 

If you are at the Lindsay International web site to learn more about the application of DNA testing to further your understanding of your Lindsay genealogy,  I will strongly encourage each visitor to thoroughly review the extensive material posted there.   Upon doing this, it is hoped that a representative of each Lindsay lineage of the world will recognize the need to participate in Y-Chromosome DNA testing, via the International Lindsay Surname DNA Project.  In any event, your participation should be based on your personal basic knowledge of molecular genetics and DNA testing and the potential benefits it can provide to you.  You might wish to start with the Human Genome Project.

From all the historical accounts, the Lindsay surname first appeared in Scotland, on the charters of Prince David of the Cumbrians (later King David I), during the years 1116 to 1120 CE.

We are cognizant of the fact the International Lindsay Surname DNA Project will require a broad based, global participation from those of the Lindsay surname if we expect to be fully successful in determining the full range of founders of the Lindsay surname along with their appropriate Y-chromosome haplotype.  Currently (February 2017) participating in the International Lindsay Surname DNA Project are 293 individuals from  Lindesay/Lindsay/Lindsey/Linzee/Linzey lineages in Australia, Canada, England, Germany, New Zealand, Republic of Ireland, Northern Ireland, Scotland and many of the United States.

From this group of worldwide Lindsays, we have currently identified twenty (22) specific DNA Groupings of biological/genetic cousins.  We can say without any doubt that those participants, and the Lindsay lineages they represent, within each unique DNA Group, share a common ancestor at some point within the timeframe whereby surnames came into common use among the general population.  Although it varies with the many surnames of Europe, the common use of surnames is believed to have occurred in the 1500 to 1600s.  Because of their prominence, the use of the Lindsay surname came into use in Scotland in the early to mid-12th century.

It becomes obviously apparent, from the accrued data, that we need more participation in the Lindsay DNA Project from the countries of origin (Scotland & England) of our Lindsay surname in order to ascertain the Y-chromosome haplotype of those indigenous Lindsay lineages which have always resided in the "country of origin".  Our DNA conclusions are without doubt currently skewed toward the descent of the surname in the United States as a result of the number of participants that come from Lindsay lineages that reside in the United States.   I strongly encourage more participation from those of the Lindsay (regardless of how it is spelled) surname residing in Scotland and England which will help in generating a truly international genetic view of the Lindsay surname.  Increased participation from those of the Lindsay surname in the UK will also help us to assure that we have "discovered" as many as possible of the indigenous founders of the Lindsay surname in the geography in which the Lindsay surname historically first appeared.

The best recommendation that I can make for you, to possibly learn more about your Lindsay lineage, is to participate in the International Lindsay Surname DNA Project.  There are many Lindsay genealogical lineages that have already identified their Y-chromosome DNA haplotype.  If you could match up with one of these Lindsays, there is a good possibility you could learn much more than you already know regarding your descent from your Lindsay ancestors.  

In order to be able to compare 100% of your Lindsay Y-chromosome DNA results to all the other Lindsay DNA participants who have already been tested, it will be necessary for you to be tested for at least the same slate of 43 Y-chromosome STR markers that is currently used by the Lindsay Project.  Thus I strongly encourage you to use this Project for any Lindsay genealogical DNA testing that you might consider. 

It would be very meaningful for a male, bearing the Lindsay (regardless of the spelling of the surname Lindsay) surname at birth, to establish the Y-chromosome DNA haplotype for his Lindsay lineage.  This would give him the opportunity to compare his Lindsay lineage Y-chromosome DNA, now and at any time in the future, to other Lindsays (regardless of the spelling of the surname) in the International Lindsay Surname Haplotype Database http://www.clanlindsay.com/dna_test_results.htm and arrive at the conclusion as to which, if any, he is most likely to share a common ancestor.  It would also be a legacy for his family for generations to come in the event the male heirs of his lineage should die out. 

If you are a female, descending from a Lindsay lineage, it will be necessary, since we test DNA markers found only on the Y-chromosome, that you identify a male participant for testing, bearing the Lindsay surname at birth and descending from your Lindsay lineage.  

In due time and with the addition of new participants, the International Lindsay Surname haplotype DNA database will expand and hopefully represent most of the Lindsay/Lindsey/Lindesay/Linzee/Linzey lineages from around the world.  It is our ambition that at some point we will be able to easily match any Lindsay (regardless of the spelling of the surname) tested to a particular Lindsay/Lindsey lineage DNA grouping that has an extensive documented genealogical history.

If you are not aware, the Y-chromosome is passed down by the male to his male heirs only.  Thus the Y-chromosome possessed by a male only would be the same as that of his father, grandfather, etc., with infrequent, genetically predictable, mutations.  This has come to make the Y-chromosome a very useful tool in helping to determine surname ancestry.  The allele values found at the 43 Y-chromosome markers we measure will not provide us with the name of any one of our ancestors, but it will tell us, without any doubt, if we share a common ancestor with another Lindsay lineage that has already been DNA tested.  This would help to point us in the right direction as to where we should spend our genealogical research time in verifying the needed traditional paper trail. We all hope to be lucky enough to match 43 out of 43 Y-chromosome markers with another International Lindsay DNA Project participant who also has a well documented Lindsay genealogy.  

The resultant allele values measured for our specific slate of 43 Y-chromosome STR markers will become the Y-chromosome haplotype for your Lindsay lineage.  

The test process is very simple.  A participant will be provided with a DNA Sample Kit containing a packet of three, Q-tip type, swabs which will be used to swab the inside of the cheek of the mouth (no blood required).  These swabs are then placed, by the participant, in the container provided, and returned to the laboratory for testing.  When the test results have been provided, the Project Administrator will analyze your data against the current Lindsay database searching for matches with other Lindsays who have already been tested.  You will receive the results of that analysis in an e-mail from the Project Administrator.  Keep in mind there is no guarantee that your Lindsay DNA will match any of the other participants tested thus far.

Up until recently, the International Lindsay Surname DNA Project used one of two DNA testing companies/laboratories.  The most notable is Family Tree DNA (FTDNA), located in Houston, Texas, for their business longevity and commitment to the genetic genealogy community and the other is AncestryDNA (Ancestry.com).   AncestryDNA has chosen to withdraw their Y-chromosome STR marker testing from the marketplace.

Family Tree DNA (FTDNA) has a 12, 37, 67 and 111 STR marker tests.  Several of the 43 STR markers used by the International Lindsay Surname DNA Project are found in each of these FTDNA tests.  The FTDNA 111 STR marker test is required to obtain values for our complete 43 markers.  The current cost of the FTDNA 111 STR marker test $339.00 .

If you wish to participate in the International Lindsay Surname DNA Project,  send me your full name or the full name of the person to be DNA tested, postal mailing address and a telephone number where you can be reached in the event your e-mail address fails.  E-mail the preceding to Ron Lindsay, Project Administrator. 

After you have provided the Project Administrator with the information above, the Project Administrator will provide you with complete details as to how you can participate in this historic family Project.  It will take approximately 6-8 weeks after the laboratory receives your DNA sample to provide you with the results. 

It is important that you know that the Project Administrator of the International Lindsay Surname DNA Project does not receive any portion of the laboratory fee.  My reward is seeing the database grow with the hope that the knowledge of my own DNA Group 3 Lindsay lineage will be expanded genealogically from one or more of the DNA profiles listed there, which has indeed been the case. 

Once your DNA results have been received by the Project Administrator, he will assign the unique L# and perform a comparative analysis against the Lindsay database of all the current participants.  You will be provided with a report of this analysis.  If you match other Lindsay participants in the database, you will then have an opportunity to dialog with any or all of the other participants that you wish regarding where their specific Lindsay genealogy might connect with your genealogy and hopefully determine the name of the Most Recent Common Ancestor (MRCA).

Although there are hundreds of markers found on the Y-chromosome of the male, keep in mind that this Lindsay DNA Project tests for a specific slate of 43 of these markers.  For any Lindsay male to be able to compare his complete Y-chromosome DNA results to that of the Lindsays who have already been tested, it would be necessary that you test for the same 43 DNA markers.  Before you decide to be DNA tested with another laboratory or another surname Project, please contact me for details of the markers of our Project.  You can e-mail me by clicking on my name found in the next paragraph.  As our database grows in size, it is anticipated that any Lindsay/Lindsey male who is DNA tested hopefully will match with one or more well documented Lindsay lineages that already exist in the "International Lindsay Surname Haplotype Database". 

Please feel free to contact the webmaster and Project Administrator, Ron Lindsay  if you have any questions regarding your participation in the International Lindsay Surname DNA Project.   Even if you choose not to participate in the DNA Project, it would still be very helpful to receive your comments, regarding this historic Lindsay* Project.
