The farm has two such sources, which supply us with water even today. The first mentioning of the farm in a written source that we know of is from 1520, but the farm is probably older. Farms with such names normally dates back to late Viking age, that is the period between years 800-1000. Such roads were established by the church in the 12th century to facilitate travel between the different dioceses.
Farms adjoining such roads are normally older than, or established at the same time as, the roads.
A possible reason why the farm is not found in written sources prior to 1520, could be the Black Death. A large number of farms were deserted, the last of these being resettled only in the late 1600-hundreds. It is therefore not unlikely that Kaldor could have been deserted until the beginning of the 1500-hundreds. Guttorm took over the farm around 1670 and married Sigrid from the nearby Hunder farm in 1671. We do not know why the farm passed out of this family s ownership, but it is tempting to believe it had something to do with the struggle for Kaldorsetra.
