Individuals who descend from the same maternal lineage have the same mtDNA profile

The Science

Two types of DNA markers are used by genealogists to trace family lineage: mtDNA markers and Y-DNA short tandem repeat markers.

King Sven’s DNA profile was obtained in 2007 when a DNA investigation was performed to determine the identity of the skeleton presumed to belong to his mother Queen Estrid, the daughter of King Sweyn I of Denmark. 

This web app compares your mtDNA profile to the last Viking King to see whether you descended from the same lineage.

Frequently Asked Questions

Do I need to have mtDNA and/or Y-DNA makers to use this free web app?

Yes, this web app is only available to users who have taken the mtDNA and/or Y-DNA STR Test. Once you have mtDNA and Y-DNA markers, you can have limitless free access to more DNA Access -powered free web applications from a variety of ancestry categories like royalty, world leaders, founding fathers, forensic finds, and more!

How do I use this web app?

DNA Access will let you know when your mtDNA and/or Y-DNA STR marker results are ready. Testing begins as soon as samples arrive at the laboratory, and the results are released and uploaded immediately to your user account once testing is complete. You can simply log into your DNA Access account to access all the free Ancestry web app.

Do I need to have an account with DNA Access to use this free web app?

Yes, DNA Access works with user accounts. If you have already taken the mtDNA and Y-DNA STR test, you can simply sign in to your DNA Access account to view your match results on the web. If you have not tested your mtDNA and/or Y-DNA STR marker, you will need to create a DNA Access account with the registration key on your test kit.

Who performs analysis on my DNA data?

DNA Access performs analysis on your DNA data. To get more markers, upgrades can be ordered directly from your DNA Access user account. All prices shown are in U.S. dollars, and all orders will be charged in U.S. dollars.

I am a female, can I still match against the Y-DNA profiles in this web app?

Both males and females can take the mtDNA test to trace their maternal line. Only males can take the Y-DNA test to trace their paternal line because only males have Y-DNA. For a female to trace her own paternal line, she would need to test a paternal relative, such as her brother, father, paternal uncles (father’s brother), paternal male cousins (father’s brother’s sons).
