Take a deeper look at the most recent aDNA study from Scandinavia, and see if you’re connected to any of the ancient individuals sampled.
It is Viking season again, and we are not talking about the new Netflix series ‘Vikings: Valhalla’. The new year kicked off with a brand new ancient DNA (aDNA) study from Scandinavia. These studies are some of the most popular among our customers.
Let us start off like the Netflix series, with a quick recap of the previous studies on the topic of aDNA from Viking Age Scandinavia:
- Comparing Ancient DNA Preservation in Petrous Bone and Tooth Cementum (Hansen et al. 2017)
- Ancient genomes from Iceland reveal the making of a human population (Ebenesersdóttir et al. 2018)
- Genomic and Strontium Isotope Variation Reveal Immigration Patterns in a Viking Age Town (Krzewińska et al. 2018)
- The genomic ancestry of the Scandinavian Battle Axe Culture people and their relation to the broader Corded Ware horizon (Malmström et al. 2019)
- Population genomics of the Viking world (Margaryan et al. 2020)
- The population genomic legacy of the second plague pandemic (Gopalakrishnan et al. 2022 – Data not yet available)
Most of these studies have already been analyzed by FamilyTreeDNA’s phylogenetic specialist, incorporated into the Y-DNA haplotree, and made available on the Discover reports so that anyone with a Y-DNA haplogroup can see how they are distantly related to the ancient remains from these studies.
The Newest Study in Scandinavian aDNA
The new study by Ricardo Rodríguez-Varela et al., titled “The genetic history of Scandinavia from the Roman Iron Age to the present.” The study includes 64 new archaeological samples, mostly from present-day Sweden. 35 of the ancient individuals studied were male, and thus we could analyze their Y-chromosomes and compare them with FamilyTreeDNA’s large database of high-coverage Big Y results. Additionally, the study resequenced samples from the Krzewińska et al. 2018 study about the Viking Age town Sigtuna. While we do list both Y-DNA and mtDNA, for our purposes here, we will focus on the Y-chromosome comparisons.
Many have reached out curiously about the detailed information for each sample and how they relate to Big Y testers. We will expand into more technical details in the future.
For this breakdown, we will list the location, age, Y-DNA haplogroup, mtDNA haplogroup, and any important information we found while comparing samples. We also use the Time Tree to show the samples on the Y-DNA haplotree.
The aDNA test results have high coverage, which greatly helps when comparing results. We could identify many connections between the ancient remains and present-day Big Y testers!
Iron Age Sweden
The oldest samples in the study are labeled Pre-Viking and date to the Scandinavian Iron Age (ca. 500 BCE until 800 CE). The study included six male samples from the Iron Age ringfort Sandby Borg in Öland, Sweden. Genetic genealogist and project administrator Mats Ahlgren notes that aDNA from this time period is rare because bodies were usually burned during burial, while the Sandby Borg bodies were left unburied.

Medieval Sweden
The study includes four male medieval (ca 800-1521 CE) samples from the island of Frösön, which is named after the Norse god Frey. The island is known for having the most northern runestone in the world.
The study describes the archaeological site:
The large magnate’s farm Västerhus was located on the island Frösön, Jämtland, in northwest Sweden. The lord and his family at Västerhus are believed to have served as representatives of the king and to have had a fiscal role in the region.
The churchyard has been dated from the 11th to the 14th centuries. In the churchyard, women were buried to the north of the church and men to the south, and a hierarchical social order of the buried has been assumed to reflect contemporary Norwegian laws.

Historical Naval Sweden
It is interesting to see connections to the Iron Age and Viking Age, but of course, it is virtually impossible to establish a genealogical connection to any person who lived before the historical records. So it will be very interesting to see if we can eventually find any closer Big Y connection to the samples in the study labeled “post-medieval,” which could help identify who they were.

Conclusion
By comparing the excellent aDNA results from the new study with present-day high coverage Y-chromosome results from Big Y testers, we discovered many interesting patrilineal connections between the past and the present. As more people test, we expect to identify many more connections, and the placements on the Y-DNA and mtDNA haplotrees will be updated accordingly.
Although this study almost exclusively focused on aDNA samples from Sweden, we identified connections to customers from many other countries.
We have presented the information from the analysis with a lot of detail in this blog article. Comment below and let us know what you think about this type of detailed reporting of aDNA studies and what you would like to hear more about.
I find this very interesting and looking forward to hear more about it.
While all this is good to know if one can decipher it, has anyone done a video for U-tube to show us how to actually use it. Also, it seems like all this is geared towards those that have done the the Big Y 700. My husband has done the Big-Y 500, but we never see anything on this, so I guess it was a waste of money. Yes, we can upgrade at about $200 more, but we never got anything out of the 500. It was just abandoned. Are there any videos that explain just exactly where we go to find this above info, and what and how can we use it on an individual basis?
Hello!
We’re sorry to head about your frustrations with the Big Y-500. You should still be able to use your Big Y-500 haplogroups in the Discover reports. Are you able to see the “Discover More” button in your dashboard?
Most interesting information. Would definitely like to see more results presented in a similar fashion. This definitely adds value, so keep on.
Hi
Thanks for this update!
I See that my Kit No. 717104 connects to Sandby Borg 18 (snb018).

Ulf
Very interesting! FTDNA should do this kind of comparision also into a Viking Age samples from UK and Denmark.
Absolutely fascinating. Enjoyed the detail.
I no longer have my father or uncles to DNA test for Y-DNA, only a male cousin, but he is not interested…
Can see I match to many (already three from Sandby Borg) of the samples above from my results by MTA, My True Ancestry.
As they, MTA,can match me would you, FTDNA do so as well even if I do not have access to my Y-DNA?
Kindly, Christina Svensson
