Olof Nilsson Stjärna / Star of Kopparberget, b. abt. 1420, belongs to hg R1a-CTS3402


Stora Kopparberget, the Great Copper Mountain, was a medieval mining and industrial center of Sweden. Many prominent and nobel families are ancestral of the area. Since 2001, the area is a UNESCO World Heritage.

Three brothers are mentioned at the court of Kopparberget in 1473, Olof, Markvard, and Hans. They were sons of Olof Nilsson, the most distant ancestor of what is called Stjärna Kopparbergssläkten (Star of Kopparberget) [1].

One agnatic (paternal) line to present days from the son Olof and one from the son Markvard have been tested with Y-DNA37, matching each other as expected. At the Olof line there are two matching results with a documented MRCA at the 18th century. SNP tests on one of the results demonstrates that the kin belongs to the haplogroup R1a-CTS3402.

BigY testing is required for further confirmation and perhaps indications of the pre-historic origin of the kin.


Kniva, Vika parish

Olof Nilsson lived in the 15th century in the village Kniva east of Falun in the province of Dalecarlia in central Sweden. A painting on one of the glass windows in the Vika church has been associated with Olof, thus he has been said to belong to a medieval nobility Stjärna / ”Star”. Traditionally it has been thought to be of Danish ancestry.

His sons Olof, Markvard, and Hans are mentioned in documents from the court at Kopparberget in 1473. From this one can conclude that Olof should have been born around 1420 or a little earlier.

Stiernhielmsstenen i Kniva, Vika

All three sons are known to have had descendants for several generations [2]. The son Hans should have been the ancestor of the nobilities Swedenborg and Schönström but this has recently been proved to be incorrect. [5].

The son Olof had several descendants, e.g. Hans, the ancestor of the Rottneby line.

The son Markvard was the ancestor of Georg Stiernhielm. Stiernhielm was knighted 1631 and granted the estate Wassula north of Tartu in Estonia, at that time a part of Sweden. The nobilities von Stiernhielm lived at Wassula for centuries. The last agnatic descendant Nils von Stiernhielm (d. 2003) was born at the estate.

The results can also be found in the FTDNA project Kopparberget [4].

Bengt-Erik Lind, descendant of Olof Nilsson Stjärna

The kits match normally and there are no other matches close to the group.  Jouko Lindh who has tested 67 markers has his closest match in the Sweden DNA project at gd=13 (67 markers). The large distance to other tested Swedes supports the conclusion that the three tested men really have Olof Nilsson Stjärna as a common ancestor.

SNP-tests have placed Bengt-Erik Lind in haplogroup R1a-CTS3402.


All three tested persons have approved the publishing of their names.

Thanks to Mr. Stefan Jernberg and Mr. Torsten Berglund for checking of the written records of the tested lines.
