Tora Mosterstong

[1] According to Snorri Sturluson's Saga of Harald Fairhair (Soga om Harald Hårfagre), Tora was from the island of Moster and was descended from the clan (ætt) of Horda-Kåre (Hǫrða-Kára): Da kong Harald var innpå sytti år, fekk han ein son med ei møy som heitte Tora Mosterstong; ho var ætta fra Moster.

Da det lei så langt at Tora venta seg snart, ville ho fare til kong Harald.

Sigurd jarl auste vatn på guten og kalla han etter far sin, Håkon Ladejarl.

When King Harald was nigh on seventy years old, he had a son with a maiden named Tora and was called Mosterstong; her clan was from Moster.

They lay ashore at night; there Tora birth a child on the slate by the gangplank, and it was a boy.

Snorri consistently speaks of Tora as concubine and maidservant, which tends to produce the wrong connotations.
