The Mimram Valley is named after the River Mimram, which rises from a spring to the north-west of Whitwell, in North Hertfordshire, England, and makes its confluence with the River Lea near Horn's Mill in Hertford. At Whitwell there are watercress beds which have existed since Roman times and these are fed by the same springs. The valley extends northwards where it becomes known as Lilley Bottom. Other sections of the valley are known as Kimpton Bottom and Codicote Bottom.
Although a dry valley to the north, it has been known in particularly wet years for the River Mimram to be extended for several miles by springs in the upper valley. In 2001, in a neighbouring valley to the west a village was flooded. The Valley is the furthest east of all the Chiltern Hills valleys.
The river is the subject (and speaker) of a Stevie Smith poem, The River God. Popular and enjoyable though this poem has been for its many readers, the description of the river in the poem bears little relation to the geography of the actual Mimram.
The name "Mimram" is widely believed to be of Celtic origin. For example, Rutherford Davis states "etymology unknown, but there is little reason to doubt it is Celtic". Etymological connections have been suggested with the River Mint in Westmorland and with North Mymms in south Hertfordshire. Suggestions of it being named after any Celtic deity are unlikely to stem from any academic research. However, etymologists and philologists have found the name hard to analyse as there has been so little raw material on which to work until well into the Saxon era.
Historically, the river has also been known by the name "Maran" and many maps from the 19th and early 20th centuries mark the river's name as "Mimram or Maran". Downstream in Digswell there is a homestead property dating from the 16th century that has the name "Maran House". It has been speculated that "Maran" may hark back to the homelands of the Catuvellauni tribe, the Celts who came to Hertfordshire from a region of modern-day Belgium and Northern France where the main river is the Marne, after which a whole department of France is named. The prefecture of Marne is Châlons-en-Champagne, formerly called Châlons-sur-Marne - with the name "Châlons" being etymologically derived from the local Catalauni Belgic tribe. However, the link between the French Catalauni and the British Catuvellauni is not categorically proven: some texts assume they are connected (including, most recently, Graham Robb's "The Ancient Paths"), while others infer a lack of connection from the lack of proof.
