It has been presumed, that by "two Kvenlands" here the abbot probably referred to Kvenland and Finland, as the two were both inhabited by culturally quite similar type of Finnic peoples/tribes (in addition to the Uralic Sami) that in other Islandic sources are sometimes said to have been ruled by the same kings.
It appears e.g. once in a list of countries found in Leiðarvísir og borgarskipan, which was basically a guidebook for pilgrims about the routes from Northern Europe to Rome and Jerusalem, written by an Icelandic Abbot Níkulás Bergsson in the monastery of Þverá (Munkaþverá) in the late 1150s CE.
