Marsh is a hamlet in the parish of Great Kimble in Buckinghamshire, England. The hamlet name comes from the surname Marshall; this was the name of the man who owned the manor in the 12th century. Formerly a parish in its own right, it was annexed into the parish of Great Kimble in the late medieval period when its manor was purchased by Lord Hampden (ancestor of John Hampden) who was also the lord of Great Kimble manor. In the English Civil War it was reputed that King Charles I of England spent some time in hiding in the pub in the hamlet. Today the hamlet is just a small collection of houses, a pub and a couple of farms. The name Marsh is also given to the nearby Marsh Level Crossing on the railway line that runs from Princes Risborough to Aylesbury.
