Shagrath
Birth Name: Stian Tomt Thoresen
Place of Birth: Jessheim, Akershus, Norway
Date of Birth: 18 November, 1976
Ethnicity: Norwegian
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. Shagrath (lives at Sørvaldvegen 26) and his parents (live at Lørenvegen 15) do not share the same address, but they are close (both live in 1923 Sørum) according to these links: http://www.1881.no/tlf/dimmu-borgir-stian-tomt-thoresen_100708330S0/ (Shagrath), http://www.1881.no/bygg-og-anleggsvirksomhet/bygg-og-anleggsvirksomhet-akershus/bygg-og-anleggsvirksomhet-soerum/ingar-haakon-thoresen_350402S1/ (Ingar), & http://www.1881.no/person/soerum/soerum/may-britt-thoresen_1160299S1/ (May).
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
