Y-DNA from a man from the noble family of Swedenborg has been tested and found to belong to a subgroup of I1-BY229. It is likely that this is also the haplogroup of the internationally known 18th century scientist Emanuel Swedenborg.
Emanuel Swedenborg came from one of the mining families at Stora Kopparberget. His father, Bishop Jesper Svedberg, was born on the farm Sweden a few kilometers east of Falun; the name Svedberg is formed from the farm name. He in turn descended from Otte Persson in Sundborn, mentioned in 1571.
The tradition was that bishops' sons should be ennobled, which happened to Emanuel and his brothers in 1718. They were assigned the name Swedenborg.
Emanuel Swedenborg first studied in Uppsala after which his career as a scientist, philosopher and mystic began. He died after a long life in London in 1772. He had no children but from his brother Jesper has agnatic descendants.
A descendant has been tested (FTDNA kit # 491250) and the BigY result shows that he belongs to I1-Y33685 which is a subgroup of I1-BY229. This is the I1-BY229 branch on Yfull:

Swedenborg thus belongs to branch I1-Y33685 with TMRCA, estimated time to common ancestry, 550 years before the present. Yfull in v5.05 from 30 July 2017 has placed I1-Y33685 outside BY229 but it is in fact BY229+. This will be adjusted in the next Yfull version.
The second person on Swedenborg's branch (YF02504) has roots in Hälsingland.
Is it really Emanuel Swedenborg's haplogroup?
It is easy to doubt that a single test on a living person could really be traced back to just Emanuel Swedenborg, born in the 17th century. Of course, we do not know for sure, but it is in any case quite likely that there are no unknown fathers along the line from his father Jesper Svedberg, born in 1653, to the present.
Jesper Svedberg was born in Falun but moved to Stockholm and Uppsala for work and to study in Lund. The son Emanuel was born in Stockholm and the son Jesper in Uppsala. But neither Stockholm nor Uppsala are typical I1-BY229 areas, the group has its concentration further north in Sweden. In addition, the lineage moved further south and came further and further from the areas where BY229 is usually found.
Since the haplogroup is normal for the origin in Dalarna but less likely for the areas where the family has later been, it is quite likely that it is actually Jesper Svedberg's haplogroup from Sweden.
Emanuel Swedenborg died in London but since 1910 rests in a sarcophagus in Uppsala Cathedral. His skull was auctioned in 1978 at Sotheby's for £1,500 to be reunited with the body.
The results are in the FTDNA project Copper Mountain and in the Yfull group Kopparberget
