Shagrath is a Norwegian musician. He is a vocalist, founding member, and multi-instrumentalist of symphonic black metal band Dimmu Borgir. Galder, Silenoz, and Tjodalv are or have also been members of Dimmu Borgir.
I suspect that his parents are May Britt and Ingar Håkon Thoresen.
This is the genealogy of Ingar Håkon Thoresen: http://www.geni.com/people/private/6000000006239517384
Hopefully, the relationship between Shagrath and his parents will be proven.
May’s maiden surname is Fjelstad.
Correction: Fjeldstad
