A Quarterland or Ceathramh (Scottish Gaelic) was a Scottish land measurement. It was used mainly in the west and north. It was supposed to be equivalent to eight fourpennylands, roughly equivalent to a quarter of a markland. However, in Islay, a quarterland was equivalent to a quarter of an ounceland. Half of a quarterland would be an ochdamh(ie.one-eighth), and in Islay a quarter of a quarterland a leothras(ie.one-sixteenth). The name appears in many Scottish placenames, notably Kirriemuir. Kerrowaird – Ceathramh àrd (High Quarterland) Kerrowgair – Ceathramh geàrr (Rough Quarterland) Kerry (Cowal) - An Ceathramh Còmh’lach (The Cowal Quarterland) Kerrycroy - An Ceathramh cruaidh (The Hard Quarterland) Kirriemuir – An Ceathramh Mòr/Ceathramh Mhoire (either "The Big Quarterland" or "Mary’s Quarterland") Ceathramh was also used in Gàidhlig for a bushel and a firlot (or four pecks), as was Feòirling, the term used for a farthlingland. Isle of Man The Isle of Man retained a similar system into historic times: in the traditional land divisions of treens (c.f. the Scottish Gaelic word trian, a third part) which are in turn subdivided into smaller units called quarterlands.
