Crawford Y-DNA Project

If you are considering purchasing a test from FTDNA,
PLEASE
FIRST click this link to >> Family Tree DNA <<

Your purchase will accrue a small percentage to the Crawford Surname Y-DNA Project, at NO COST to you. This simply sets a cookie in your browser that lasts 1 week. You won't see any special notice. The use of the funds to help purchase future tests will be determined together by the main project volunteer administrators, following criteria approved by the Clan Crawford Association's Executive Committee, and there will be a periodic review to ensure proper use of the funds.(1)


Sales: FTDNA's "Holday Sale" has been extended! This sale ends 3 January 2022 (at 11:59 PM Pacific Daylight Time).

As always, if you're considering a test:

  1. Click the Crawford Project's "affiliate link" noted above.
  2. If you are getting Big Y for a Crawford, the Crawford Project will happily cover $50 of the cost using credits already earned thanks to (1) above & donations... Contact me for logistics (see below).
  3. If you're a prospective new Crawford Y-DNA tester, and you're in Scotland or Northern Ireland, or have genealogy that solidly documents your roots there, you may qualify for an additional discount on a new Y-DNA37 (or higher) test. Contact me to discuss, if interested (see below).

—Dave Nicolson, volunteer admin for the Crawford Surname Y-DNA Project

To discuss the incentives noted above, contact Dave Nicolson for further info!

Specific instructions are below.


NEW TESTERS:

We recommend the Y-DNA37 test (regular price via project $119 as of 1/2020) or higher (the 111 test cost more but give more power for matching and grouping in the project; upgrades can be ordered at any time). Big Y-700 is ideal, but expensive, though the cost includes the Y-DNA111 (!!). You can get any available sale discounts AND automatically join the Crawford Y-DNA project if you:

  1. Click the link highlighted above (this one), then close that window (this just sets a browser cookie as noted, it silently benefits the Crawford Y-DNA Project).
  2. Select your test and purchase from this page.
     

CURRENT FTDNA members:

  1. Click the link highlighted above (this one), log into FTDNA (if you have not already done so), then close that window.
  2. If you have not already done so, join the Crawford Surname Y-DNA Project by clicking the "JOIN" button on this page, then close that window.
  3. Select your test and purchase from this page, noting the following:

• If you do not already have a Y-DNA test from FTDNA, please consider the Y-DNA37 (or higher, or even Big Y-700).

• If you have already taken the Y-DNA37 (or higher, especially), you should seriously consider the "Big Y-700", which is now called Big Y-700 test (link takes you to info if you're logged in at FTDNA). This doesn't check specific spots on the Y chromosome, rather it completely sequences most of the usable parts of the Y chromosome, covering over 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!). Big Y-700 prices are lower if you already have Y-STRs tested (e.g., Y-DNA111 or Y-DNA67) since it also includes an upgrade to Y-DNA111 test level. We recognize this test is not cheap, but it can give us a much more reliable view of how you are related to other testers. And note that the regular price dropped significantly in 1/2020.

• If Big Y-700 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 from any level to Y111, if it is feasible), and consider some targeted SNP testing (please ask for guidance, don't do this blindly!).
 

DNA TRANSFERS:

For those who have been tested by Ancestry.com, 23andMe, or other laboratories, your DNA results can often be transferred to Family Tree DNA for a minimal or no cost. This will put you into the FTDNA database and allow you to join the Crawford surname project. We will then be able to assist you in finding connections to existing lineages and Y-DNA matches (if you purchase a Y-DNA test).

ALSO, some of these tests include (but may or may not tell you) some Y-DNA SNPs that can be valuable to at least place your Y-DNA haplogroup at a basic level. This can inform your further Y-DNA testing choices. 23andMe explicitly reports your Y-DNA haplogroup (e.g., I-Z140, R-M417, etc.). AncestryDNA includes a fairly small number of Y SNPs in their autosomal test (e.g., R-L20, I-Z140, etc.), but they don't report it; but you can download your raw data and determine the Y-SNPs they tested using a free tool from the genetic genealogy community here (use option #2 at the bottom, and upload your raw data file, the Y-DNA info will be in the first line of the results). Contact the Crawford DNA lead, Dave Nicolson, if you need help, and to report your Y-DNA SNPs. This is valuable information for the project!

(1) - Although the CCA fully supports the goals of the Crawford Y-DNA Project at FTDNA, it has no direct control over how the funds deposited into the Project’s General Fund (held by FTDNA) are spent. However, the CCA will maintain oversight 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 volunteer administrators. Please see the August 2017 CCA Newsletter for further information about this arrangement.
 


WELCOME TO THE CRAWFORD Y-DNA PROJECT

The Clan Crawford Association has collaborated with Family Tree DNA (FTDNA) to produce the Crawford Surname Y-DNA 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 Short Tandem Repeats (STR) "Y-DNA37" test (or higher, as the Y-67 and Y-111 provide more power for matching and grouping members) from FTDNA. However, SNP (Single Nucleotide Polymorphisms) testing is playing a growing role in dissecting project lineages. You may find some useful information on the Crawford Project's "Links" page, here:
https://www.familytreedna.com/groups/crawford/links

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).
 

MEMBERS-ONLY Y-DNA REPORTS:

In addition to the project's public Y-DNA Results page at FTDNA, we also have a "Y-DNA Analysis (Members Only)" section on the CCA site in the Y-DNA tab that will allow members of the Clan Crawford Association to view and download special reports concerning STR and SNP results related to specific lineages or haplogroups. The members-only page is here:
https://clancrawfordassoc.org/dna-members

These reports are not available to non-members in order to protect privacy. We are exploring options for providing access to these reports for members of the Crawford Project at FTDNA who are not also members of the CCA, and hope to bridge this gap in the future.

Participation in the Crawford Surname Y-DNA 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.
 

The Crawford Y-DNA Project, Going Forward

The Crawford surname project has over 660 participants at this time, including roughly 400 who are Y-tested Crawfords (as of 11/2020), but many more are needed to obtain an adequate sample of Crawfords to draw major, firm conclusions. We are encouraging all Crawford men to have their Y-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, Ireland and Northern Ireland, and people with well-documented descent from any of the numerous established Crawford families from the 1600s and before. From such expanded testing, we hope to facilitate those without such "paper trails," on all the continents, to obtain linkages to their ancestral home, bringing Crawfords together from arround the world.

We have made significant progress in delineating and identifying specific ancient Crawford lineages using SNP information derived from the Big Y-700 test and other advanced SNP tests provided by Family Tree DNA and YSeq.net, and with the help of external results analysis at Ytree.net ("The Big Tree" is free but only for one particular haplogroup, R1b-P312) & YFull.com (not free, but very sophisticated and useful analysis reveals SNPs that others miss). We are seeing more and more lineages within their own defining Y branches and are also separating multiple sub-lineages within such groupings. 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-700 will reconnect the lost paper trails and allow them and us to understand how we are related.

Within the Crawford Surname Project the haplogroups A, 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. Periodically, as new analyses are completed, some individuals may find that they have been placed in a different lineage while others may find that they are no longer in a lineage but have been put back into an Ungrouped category. This will probably be a short stay as more individuals join the Crawford surname Project and future analysis connects new relationships.
