Thorljot of Rack Wick

http://en.wikipedia.org/wiki/Olvir_Rosta

The 19th century historian Joseph Anderson was of the opinion that Rekavík likely refers to Rackwick on the island of Hoy, Orkney; or possibly, but less likely, to Rackwick on the island of Westray, Orkney.

Has anyone considered the possibility that he was an Icelander from Reykja(r)vik? Icelanders had been traveling out from their colony and making their presence felt in the wider world for some time.
