such research can be fascinating and intriguing. there are approximations to my meadow plot referenced in the National Archives, Kew: http://www.british-history.ac.uk/report ... mpid=64493 (some documents my be held in local county archives offices).
The above record link is a page mainly for Cheshire, but the page is searchable for other counties.
In my local office I found a 1760s estate map with a lot of the hedgerows in the same locations and the plot holders named for field strips.
