The Well-man of Sverresborg

The Sverris saga records that when Sverresborg castle fell in 1197, the attackers threw a dead man into the well to poison it. Eight hundred years later, archaeologists found him — and his genome made him the first person from a Norse saga ever identified in the flesh. He was a blue-eyed, fair-haired man from southern Norway, casually sacrificed for a siege tactic and immortalized by accident.

The genome-wide data behind this entry was published in Corroborating the Sverris saga with ancient DNA.

Every Ancestrify Global25 report includes the free Notable Matches lens: your coordinates are compared to every sequenced member of every catalog entry, and the distance to the closest member is reported — a Euclidean distance in the same 25-dimensional space the Distance lens uses. Because this is a single real individual, not a population average, distances naturally run larger than population distances — that is expected, not a poor result. And one thing is never claimed: a small distance means similar ancestry composition, not that the Well-man of Sverresborg is your ancestor.

  Who was the Well-man of Sverresborg?

  The Well-man of Sverresborg (d. 1197 CE, Trondheim, Norway) is one of the Historical figures entries in our Notable Matches catalog, represented by one sequenced ancient genome published in the study "Corroborating the Sverris saga with ancient DNA".

• 02

  What does "matching" the Well-man of Sverresborg mean?

  Your Global25 coordinates are compared to the entry's sequenced members and the distance to the closest one is reported — a Euclidean distance in the same 25-dimensional reference space the Distance lens uses. A notable entry is one person or one small burial group, not a population average, so distances naturally run larger than population distances.

• 03

  Is the Well-man of Sverresborg my ancestor?

  No — and no DNA test can show that. A small distance means your genome sits near this individual's in a shared reference space: similar ancestry composition, not descent. Ancestrify never claims a notable individual is your ancestor or relative.

  How do I see my own distance to the Well-man of Sverresborg?

  Notable Matches is a free lens on every Ancestrify Global25 report — never sold separately. Order the G25 analysis (29.99 EUR), and your report ranks your coordinates against the full catalog, with a portrait, dossier and map for every entry. The public demo shows the lens with example data.
