Vikings in Iceland

I once read that the farm name KVAM of Aurland, S&F, NO was the base name for a farm in ICELAND Not sure of the source. UNDREDAL of Aurland was the home base of the Viking whose wife was purported to be from Aurland. The source said the Viking was 'of Sogn' and, of course, 'rich and powerful'. No dates were provided - or I forgot them. Does anyone have facts or even clues re this? Directions to research references are welcome.
