About us

Due to some issues with our website and the inability to update the pages, we have elected to use FamilyTreeDNA's project website to provide you with greater detail about the Grant DNA Project  Unfortunately, we lost some of our flexibility and content, but feel that having a site is more important,

We are finding that many of our participants are changing their email address, thus we lose connection and must rely on snail mail to reach out to others for information.  If you have changed your email address and did not notify one of us (co-administrators), do both of us a favor and send a quick email advising us of your email address change.  Thanks.

Most recent DNA news:

As Administrators of this project, one of the most frustrating aspects we run into is the large amount of bad info on the internet in regards to "reading" the results published here.  Much is well out of date, such as http://www.clangrant.org/index.aspx?pid=4 from the official Clan Grant site.  It seems like now is a good time to clear some things up.  The DNA has never "conclusively vindicated the Grant Seannachies of the past who were unanimous that the original Grant Chiefs were of Viking stock."  The original Grant Chiefs may have been Viking, Norman, Anglo-Saxon, French, German, Frisian, Celtic, Danish, Norwegian, Polish, or even other "stocks" as the their main DNA signature group can be found in any of those peoples.  There has always been a Norman vs Viking debate within the Clan over the years (or at least since Fraser's book).  Or at least it seems this way.  I am not a Clan Historian nor do I claim to be an expert on the Clan's history.  I am unconcerned with these histories other than comparing them to what the DNA tells us.  The DNA is very clear that the Grant Chiefly line is NOT related to the Royal Stewart family via male yDNA.  It is 100% clear about this.   Does this disprove Andrew Stewart's existence?  Not in the least.  But it does prove that if the Andrew Stewart did assume the name and change the male line of Grants, he surely was not related by blood (father to father) to the Royal Stewart family.  The DNA also cannot distinguish between Norman and Viking ancestry.  Keep i mind, the Vikings were the grandfathers of the Normans genetically.  They are of the same "stock."  The Angles, Saxons, Jutes, Frisians, ect., are also of the same "stock."  We can assume that many different halpogroups would be present in these populations.  There is no one signature that defines ANY population base or ethnic group from history unless you are going back 20,000 years and looking at very specific human migrations that pre-date Western Europe altogether.

Because it is unrealistic for any of us Admins to correct the various websites with misleading information on them (and we have tried, including contacting the source of the clangrant.org article), we strongly encourage you to check here for reliable DNA information as it pertains to the various branches of the Clan Chiefs family tree as well as other unrelated Grant lines.  If it is important to know whether or not you are related to a specific Grant line, please email us and ask.  We would be happy to compare notes for you.  Or check the DNA results website which has been carefully organized and endorsed by several DNA experts as well as Admins from other projects (including the Stewart DNA Project Admin) as being factual and reliable.

If you want to confirm a yDNA family connection to the Grant family of the Clan Chiefs, a Z17274 SNP test will confirm that connection without a doubt.  Z17274 is at least 600 years old and only found by members of this family, including the current Chief as well as the heads of the Grants of Dalvey, Glenmoriston, Shuglie, Corrimonie, Tullochgorm, Blairfindy, Craskie, Kilgraston, and the "MacRobie" Grants who settled the Trois-Rivieres area of Canada and are likely the oldest confirmed branch of this Grant tree.

A massive re-org of the DNA results groupings has been finished as of late April 2017.  Be sure to check and see if you've been moved.  

Our pending Kilgraston Grant Big Y has come back, and they surprised us with a positive score on R-Z21133, showing that the Grants of Glenlochy, ancestors of the Grants of Kilgraston, descend from a more recent Clan Chief than expected.  A Big Y is now pending on our Dalvey kit.  Thanks to those of you who have made donations to the general fund over the years!!

The Blairfindy (Longueuil) kit has tested positive for R-Z21133.  This was expected.

Craskie has been confirmed as a Glenmoriston tree member.  They both share R-A1226 & R-A1227 exclusively (meaning nobody else has these SNPs so far)

The MacRobie Grants are confirmed descendants of an early Clan Chief and are to this point the most distant confirmed branch of Grants within that family tree.  They have exclusive SNPs R-A1324 & R-A1327 as well as share the Clan signature SNP R-Z17274.

Our New Blog Site

Recently, a Blog site was added as a way for the co-administrators to expand their thoughts on topics of interest, observations from the test results, groupings, specialty tests, etc.  To access the blog, click on the following link.  At this time, you cannot reply with comments.  This site is a work in progress, so you don't expect it to be robust at this time.  Feel free to send an email to us with your comments.


Our Discussion Group

We created a Yahoo Discussion Group for the Grant DNA Project.  It is a public forum, but you must register and be accepted to participate in the discussions.  Below is the link to the discussion group.

Clan Grant - Canada Website

Penny Grant has created a website that is specific to the Grant Clan in Canada.  If you are a Grant with a Canadian background, you may find this site useful to your search.


How It All Works

The project data is based on testing "alleles" from certain "loci" on the Y-Chromosome (called Y-STR values, for Short Tandem Repeats - a recurring pattern at that position). The Y-STR "count" at each position is displayed as a number. These allele numbers are rendered for anywhere from 12, to 25, 37, 67 and 111 different loci positions on the Y-Chromosome that have been determined to have very low mutation probabilities, meaning that these values will be passed on along a given biological line with relatively few if any mutations for thousands of years.

The Septs

Over the years, many surnames have come to be associated with that of Grant. Such traditions have probably arisen from individual families with these names living in Grant territory during clan times. However it is clear that some (such as Cairns, Bisset, Suttie, etc.) are those of independent families in their own right from very early times. It must be made clear, therefore, that having such a name does NOT, , imply any connection with the Clan Grant at all. (more---->)


You do not need to belong to any society to participate in the Grant DNA Project, though you may find that one or more of the societies of interest as you search for your Scottish heritage.

Below is a link to a website authored by Donald Cameron Grant Gill which includes a substantial section devoted to the Grant of Strathspey from William Grant 1733 to Cheeryble Grants and today:  http://www.gillfamily.co.za
