Family Tree DNA

Y-DNA Project

If you decide to purchase a test from FTDNA, PLEASE FIRST click this link to > > Family Tree DNA < <, as your purchase will accrue a small percentage to the Crawford Surname Y-DNA Project, at NO COST to you. The use of the funds to help purchase future tests will follow criteria approved by the Clan Crawford Association's Executive Committee, and there will be a periodic review to ensure proper use of the funds.*


We recommend the Y-DNA37 test (regular price via project $149) or higher (the 67 and 111 tests cost more but give more power for matching and grouping in the project; upgrades can be ordered at any time). You can get any available sale discounts AND automatically join the Crawford Y-DNA project if you:

(2) Purchase from this page.

    CURRENT FTDNA members:

(1) If you have not already done so, join the Crawford Surname Y-DNA Project by using the sign-in link on this page.
(2) Click the link highlighted above.
(3) Decide what test to take...
• If you do not already have a Y-DNA test from FTDNA, please consider the Y-DNA37 (or higher).
• If you have already taken the Y-DNA37 (or higher), you should seriously consider the Big Y test (link takes you to info if you're logged in at FTDNA and have Y-DNA12 or higher done) ... This doesn't check specific spots on the Y chromosome, rather it completely sequences most of the usable parts of the Y chromosome, covering around 10 million locations! It includes almost all known "SNPs" (inheritable markers passed from your male line ancestors) and those never before seen in others (your line's newer markers!). This advanced test is regular price $575, which we recognize is a lot, but it can give us a much more reliable view of how you are related to other testers.
• If Big Y is simply not an option due to price, please do consider an upgrade to your Y STR test (anything below Y37 should be upgraded to at least that level, and everyone can think about upgrading Y37 to Y67, and Y67 to Y111, if it is feasible)

* - Although the CCA supports the goals of the Crawford Y-DNA Project at FTDNA, it has no direct control or input into how the funds deposited into the Project’s General Fund (maintained by FTDNA) are spent. However, the CCA will maintain a close observation of the use of that General Fund, to ensure there is no abuse or misuse of the funds generated by the purchase of DNA test kits by CCA members, or non-CCA members that would discredit the CCA, its membership, the Project or its administrators. Please see the August 2017 CCA Newsletter for further information about this arrangement.



The Clan Crawford Association has collaborated with Family Tree DNA (FTDNA) to produce the Crawford Surname Project. FTDNA has the largest Y-DNA database in the world and has the greatest ability to compare your DNA with others who have taken the test to determine relationships. We use the "Y-DNA37" test (or higher, as the 67 and 111 provide more power for matching and grouping members) from FTDNA, although SNP-based testing is playing a growing role in the project. The project is run by volunteer administrators, and our initial goal is to help group each member with any others who appear to be relatively closely related, and thereby allowing those groups to focus on pushing back their paternal genealogical line further, and hopefully identify common ancestors. We further hope to shed light onto the deeper connections between these groups and how they might connect through the historical Crawford lines (see the Genealogy and Clansmen tabs above).

We now have a "Y-DNA Analysis (Members Only)" section in the Y-DNA tab that will allow members to view and download special reports concerning STR and SNP results related to specific lineages or haplogroups. These reports will not be available to non-members. participation in the Crawford Surname Project does not provide automatic membership in the CCA. Join the CCA by clicking on the "Home" page and then "Join the Clan". You will then be able to click on the "Members Only" tab to access the PDF files. Non-members viewing this page will not be able to see the analysis tab.

The Crawford surname project has over 400 participants at this time, but many more are needed to obtain an adequate sample of Crawfords to draw major conclusions. We are encouraging all Crawford men to have their DNA tested and attached to the Family Tree Y-DNA database and the Crawford surname project. We are especially interested in testing more Crawford males from Scotland where we hope to obtain linkages to their ancestral home for other Crawfords in North America, Australia, and elsewhere.

We have made significant progress in the last year in delineating and identifying specific ancient Crawford lineages using SNP information derived from the Big Y test and other advanced SNP tests provided by Family Tree DNA and, and with the help of external results analysis at ("The Big Tree" is free but only for one particular haplogroup, R1b-P312) & (not free, but very sophisticated and useful analysis reveals SNPs that others miss). We are seeing more and more lineages within their own defining haplogroup and are also separating multiple sub-lineages within a lineage. As the SNP research fulfills its possibilities, we have been able to track DNA branching into modern times and we are starting to connect Y-DNA with our known paper trails. It is too early to be certain but what this could mean is that the Y-DNA participants, especially those who have taken advanced tests such as Big Y will reconnect the lost paper trails and allow them and us to understand how we are related."

Within the Crawford Surname Project the haplogroups B, E, F, I, J, and R are represented. The project continues to expand in scope and in its power to detect recent common ancestors. The number of identified lineages has grown over the years and the complexity of the I1 and R1b haplogroups have been the principle cause of additional lineages. Some individuals may find that they have changed lineages while others may find that they are no longer in a lineage but have been put back into the ungrouped category. This will probably be a short stay as more individuals join the Crawford surname Project and future analysis connects new relationships.

When you click on the following link you will see a spreadsheet with haplogroups and under the haplogroups numbered lineages. When you move your mouse over the lineage name you will see a list of kit numbers. If you haven't visited the site before you should look for your kit number or the kit number of your relative to determine under which lineage they have been placed. You then can click on that lineage and you will be taken to a lineage page that contains the STR and SNP information for the those in that lineage.
