2 Types of DNA Tests are Eligible for the Guthrie DNA Project:

• Y-DNA Testing of Guthrie men (Start with a Y37 or Y111 marker test)
• Autosomal DNA Testing of all others with Guthrie ancestry

Y-DNA TESTING

The GUTHRIE DNA PROJECT utilizes YDNA tests to discover which family lineages belong together. This is the type of DNA that is inherited from father to son straight down the paternal line. Matching YDNA means those lineages share a common Guthrie ancestor.

Yes, these tests are more expensive than Autosomal DNA tests found everywhere, but if you’re looking to discover your direct Guthrie ancestry a single YDNA test provides conclusive data that other tests cannot match.

You must be a male Guthrie in order for this test to apply. In order to assess Guthrie DNA handed down from a paternal Guthrie ancestor, the person being tested must be a male Guthrie or a male with a known direct paternal Guthrie lineage, such as an adoptee. Women do not have YDNA, so people who descend from a female Guthrie do not have Guthrie YDNA.

Y-DNA tests suitable for inclusion in the project are those at the 37 or 111-marker level. Some tests from non-FTDNA facilities may be eligible for transfer. Y-DNA testing provides you with almost instantaneous answers as to whether or not you match or don’t match one of the established Guthrie Family Groups.

Although we review Haplogroup results (ancient DNA) it must be done through the data platform at FTDNA in order to give administrators other reference data.

Partial and Full Sponsorships are currently available for eligible Y-DNA candidates for lineages found on the project’s ‘Most Wanted List’.

Group Funding may be utilized if you and your relatives want to share the cost of DNA testing in order to sponsor someone’s test.

Consider investing in your personal genealogy quest by joining the GUTHRIE DNA PROECT.

FAMILY FINDER / AUTOSOMAL DNA TESTING 

Men and women of Guthrie ancestry are able to use Autosomal DNA testing to look at your overall genetic matches. This is the type of DNA inherited from all of your family lines, but with exponentially diminishing amounts with each generation.

Percentage of Autosomal DNA Inherited from your Ancestors:
Parents: 50%
Grandparents: 25%
Great-Grandparents: 12.5%
2x-Great Grandparents: 6.25%
3x-GGP: 3.125%
4x-GGP: 1.56%
5x-GGP: 0.78%
6x-GGP: 0.39%
7x-GGP: 0.195%

Closer relations are more likely to show up as a genetic match because you share a larger percentage of ancestral DNA with them. However, some of those closer cousins may have inherited a different mix of ancestral DNA, so may not show up on your match list even though you have a rock-solid paper trail connecting you to each other. When you are trying to prove shared ancestry using Autosomal DNA it can be a challenge when you are looking for matches in those distant generations. After your original results come in, you must periodically review them for new matches. Awesome discoveries could result from the next long-lost cousin who shows up on your list.

IF YOU ALREADY HAVE AN AUTOSOMAL DNA TEST:
AncestryDNA, 23andMe and HeritageDNA test results may be transferred to FTDNA using their free Autosomal DNA Upload process. After FTDNA gives you an assigned User Name / Kit Number and Password, you may Sign In and complete a Guthrie DNA Project Join Request Form. The data transfer gives you access to all of your Autosomal DNA Matches. I do recommend their transfer upgrade (currently $19), which gives you access to additional tools, such as the Chromosome Browser, along with your ethnicity and ancient DNA results.

If unable to transfer, AncestryDNA results may still be shared with the project administrator, Ann Guthrie (Ancestry Username: AnnGU3) for analysis.

IF YOU HAVE NOT YET PURCHASED YOUR AUTOSOMAL DNA TEST:
I recommend starting with an AncestryDNA test. The size of their database eclipses everyone else. Chances are that the volume of your matches will be much larger there than any other place you could test.

Once you have results from AncestryDNA, I recommend the following:
1. Provide Guthrie DNA Project Admin AnnGU3 with ‘Viewer Access’ to your results in order to analyze your Guthrie matches and receive a report.
2. Transfer the Raw DNA File to Family Tree DNA (FTDNA) using their free Autosomal DNA Upload process in order to gain access to a second database of matches, and allowing you to officially join the Guthrie DNA Project.

The analysis of your results will include a chart showing matches to people of Guthrie ancestry, their relationship to you, shared chromosome data (if the Chromosome Browser is available), Guthrie ancestry and associated Guthrie Family Group, and whether they share any of your Guthrie matches. Background on what is currently known about your family line and their established or theorizes relationship with any Guthrie Family Group will also be provided, along with any recommendations for your personal research.
