The lands of Rankeilour were extensive, occupying the southernmost part of the parish of Monimail. They were divided into two separate holdings, Over and Nether Rankeilour, by the mid-fifteenth century. Given the tendency for affixes such as Over and Nether to be quite unstable, in the case of Rankeilour they have proved remarkably consistent (apart from the occasional Upper for Over), although Nether Rankeilour has not survived on the modern map, being represented by OS Pathf. and OS Explorer Rankeilour Mains and Rankeilour House. OS 6 inch 1st edn (1855) Nether Rankeilour is in CLS, however, on the west side of the Ballantagar Burn which forms the CLS/MML boundary, at NO325118. This probably represents an extension of the lands of Rankeilour westwards over the Rankeilour Burn into CLS. (https://fife-placenames.glasgow.ac.uk/placename/?id=3093.
