DNA and Ukrainian Genealogy: An Expert Interview with Dr. Taras Kovalenko

About Dr. Taras Kovalenko

Dr. Taras Kovalenko is a Certified Genetic Genealogist (CGG) and DNA Research Specialist based in Toronto, Ontario. He holds a PhD in Molecular Genetics from the University of Toronto and has spent 15 years helping Ukrainian-Canadian families use DNA evidence to break through genealogical brick walls. He is a regular speaker at the Ukrainian Genealogical Society of Canada and a contributor to the Journal of Genetic Genealogy.

Q1: Dr. Kovalenko, you specialize in DNA genealogy for Eastern European families. Why has DNA testing become particularly valuable for Ukrainian-Canadian researchers?

DNA testing has emerged as a crucial tool for Ukrainian-Canadian genealogical research primarily due to the historical challenges that have led to significant gaps in paper trails. Events such as World War I and II, Soviet collectivization policies, the devastation of the Holodomor, and various border shifts have resulted in the destruction of many records. Village churches, which often housed vital records, were frequently targeted in fires or confiscated by authorities, leaving researchers with scant documentation.

DNA testing circumvents these hurdles by connecting living relatives directly, bypassing the need for historical documents that may no longer exist. The Ukrainian diaspora is extensive, with communities spread across Canada, the United States, Brazil, and Argentina, creating a rich pool for DNA testing. This widespread diaspora increases the likelihood of finding living relatives who can confirm familial connections, even when documentation is missing. Thus, DNA not only helps fill in the blanks left by lost records but also provides a means to confirm genealogical relationships, making it an invaluable resource for those tracing their Ukrainian roots.

Q2: Between AncestryDNA, 23andMe and MyHeritage, which platform do you recommend for someone trying to find Ukrainian relatives?

For individuals seeking to connect with Ukrainian relatives, I recommend starting with AncestryDNA. It boasts the largest database overall, particularly strong for North American matches, which can be advantageous given the large Ukrainian-Canadian population. Once tested, I advise uploading your raw DNA data to MyHeritage, which offers a robust database for European matches, especially Eastern European ones. MyHeritage also hosts a significant number of users from the Ukrainian region, which increases the chances of finding relevant matches.

While 23andMe provides excellent ancestry composition insights, it is not as strong for finding specific Ukrainian relatives due to its smaller user base in that region. MyHeritage's "Theory of Family Relativity" feature is particularly useful, as it automatically connects shared matches to a tree, offering a visual aid in understanding familial connections. Additionally, uploading to FamilyTreeDNA and GEDmatch, both of which are free, can further expand your match pool by allowing you to make connections across different platforms.

Q3: Can DNA testing help identify if ancestors were from Galicia, Bukovyna or another specific region of Ukraine?

While ethnicity estimates from DNA tests are often too broad to pinpoint specific regions like Galicia or Bukovyna, chromosome matching offers a more precise approach. Ethnicity estimates typically provide a general sense of Eastern European ancestry but lack the granularity needed to distinguish between Ukrainian regions.

Chromosome matching, however, can be more insightful. By matching your DNA with individuals from specific Ukrainian oblasts, you can infer regional origins. On platforms like GEDmatch, you can utilize geographic clustering to observe which regions your DNA matches are predominantly from. For instance, if a significant number of your matches trace their ancestry to Ternopil, Ivano-Frankivsk, or Lviv, it suggests Galician roots. Additionally, Bukovynian ancestry sometimes exhibits a distinct Romanian admixture, which can be a clue to regional origins.

Q4: Many of our readers share ethnicity results that say 'Ukrainian' or 'Eastern European' with very little precision. How can they extract more value from these results?

To maximize the value of DNA results denoting 'Ukrainian' or 'Eastern European' ancestry, it's essential to delve beyond ethnicity percentages and focus on match analysis. Firstly, sorting your matches by the amount of shared DNA (measured in centimorgans or cM) allows you to prioritize contacting your closest genetic relatives.

Building a "match tree" is another effective strategy. By adding known relatives to your family tree, the platform can automatically extend potential connections. Shared matches can help identify common family lines, and examining surnames in match trees for Ukrainian names can provide additional clues.

Utilizing the Leeds Method is also beneficial. By color-coding matches according to grandparent lines, you can organize your matches efficiently. Ultimately, the genealogical value in DNA testing lies more in analyzing matches than in ethnicity percentages, as these connections offer practical leads in uncovering family history.

Q5: What about autosomal DNA versus Y-DNA or mtDNA for Ukrainian genealogy — when does it make sense to use the more specialized tests?

When exploring Ukrainian genealogy, understanding the differences between autosomal DNA and more specialized tests like Y-DNA and mtDNA is crucial. Autosomal DNA, which examines all ancestral lines up to 5-6 generations, is the most versatile and widely used test for genealogical purposes.

Y-DNA testing, which focuses exclusively on the direct paternal line, can be particularly useful for researching Ukrainian patrilineal surnames or for comparing men who share the same surname. This test is ideal for delving deeper into paternal lineage and is best conducted through FamilyTreeDNA, which has the most extensive database of Ukrainian participants.

mtDNA testing, on the other hand, traces the direct maternal line. While less commonly used in genealogy, it can provide insights into deep maternal ancestry. For example, certain Y-DNA haplogroups like R1a-Z280 and I2a-Dinaric are prevalent in Galicia, offering clues to regional origins. Each type of test has its place in genealogy, depending on the specific research goals and family lines of interest.

Q6: How do you approach chromosome browsing to confirm whether a DNA match shares a specific ancestor?

Chromosome browsing is an invaluable tool for confirming whether a DNA match shares a specific ancestor. Platforms like MyHeritage, FamilyTreeDNA, and 23andMe offer chromosome browsers, whereas AncestryDNA does not. By examining which segments of DNA are shared across multiple people from the same family line, you can "triangulate" a shared ancestor.

When using chromosome browsers, it's important to look for the same DNA segment shared by different relatives, as this indicates inherited DNA from a common ancestor. Generally, segments larger than 7 centimorgans (cM) are considered reliable for matching, while segments smaller than 7 cM may be false positives.

GEDmatch is another free tool that allows chromosome browsing across platforms, enabling users to analyze and compare their DNA with a broader set of potential matches. This cross-platform capability can be particularly useful for confirming shared ancestry and refining genealogical hypotheses.

Q7: Are there Ukrainian DNA databases or reference populations that you find particularly reliable?

Several Ukrainian DNA databases and reference populations are highly reliable for genealogical research. MyHeritage's Ukrainian reference population and the FamilyTreeDNA's Ukrainian project (known as the Ukrainian DNA Project) are prominent resources. The GEDmatch database also offers Ukraine-specific reference populations, providing valuable data for those seeking to understand their genetic roots.

Organizations like the Ukrainian Genealogical Society of Canada play a significant role in encouraging members to test and contribute to these databases. Academic resources such as the Genographic Project's Ukrainian data and the Human Genome Diversity Project's Belarusian/Ukrainian reference populations enhance these databases' reliability and depth.

However, it's worth noting that reference populations for Western Ukraine, including Galicia and Bukovyna, are underrepresented compared to Central and Eastern Ukraine. For those whose DNA results point to Ukrainian origins and who want to explore the regions where their ancestors lived, connecting with DNA matches through organized visits to Ukrainian regions can be a powerful complement to genetic research.

Q8: What are the most common mistakes Ukrainian-Canadians make when starting their DNA genealogy journey?

Common mistakes that Ukrainian-Canadians make when beginning their DNA genealogy journey include:

• Testing only on one platform and not exploring others.
• Expecting ethnicity percentages to precisely identify a region or village, which they typically cannot.
• Failing to build a family tree linked to their DNA results, which limits the potential for discovering connections.
• Not reaching out to DNA matches, as the matching itself is only half the work — collaboration is key.
• Confusing half-relationships and endogamy, the latter of which can inflate estimated relationship closeness.
• Not uploading raw DNA data to GEDmatch and FamilyTreeDNA, both of which offer free uploads and can significantly expand the match pool.

These errors can hinder progress in genealogical research. To complement DNA research with traditional archive sources, see our guide to choosing the right DNA test for Ukrainian ancestry.

Q9: For someone who has already tested but feels stuck, what's the single most effective next step you recommend?

If you're feeling stuck after testing, the most effective next step is to maximize your DNA's reach. Start by uploading your raw DNA data to all free platforms, such as MyHeritage, FamilyTreeDNA, and GEDmatch, to broaden your match pool. Next, examine your closest 20 matches and identify those with family trees — reach out to these individuals to collaborate on potential connections.

Simultaneously, continue building out your family tree as extensively as possible, allowing matching algorithms to connect you with known families. Joining the Ukrainian DNA Project on FamilyTreeDNA can also be beneficial, as project administrators offer guidance in interpreting results. If your brick wall is on the paternal line and you're male, consider Y-DNA testing for additional insights.
