I've been in correspondence with a brilliant documentary photographer, Simon Tasker, who was born and raised in the Langdon (Laindon) Hills, where his father owned a small farm. An uncle farmed on the marshes at Bowers Gifford, and he had an old Essex accent so broad that it was quite distinct from the variation found even only a short distance away, and which he apparently retained even 40 years after emigrating to Australia. Basildon effectively straddles both Laindon and Bowers Gifford. Simon is about the same age as me, and even in his teens in the 1970s he was driven to document what turned out to be the last days of the rural way of life that had existed for generations. Our family paths crossed - my great grandparents on both sides variously owned and ran pubs, one in the market place in Romford, and the Fortune of War on the A127, opposite which Simon's father had a farm produce shop. Another great grandfather, an entrepreneurial East-Ender who drank his way through two fortunes before dying on his third at the age of 51, built the Halfway House at East Horndon, ostensibly to quench his own legendary thirst as he was driven (in his yellow Rolls-Royce) between the Elephant in Fenchurch St and the Royal Hotel at Southend, but more pragmatically to catch the high spirited crowds of 'charabanging' East-Enders on their way to and from Southend.
Rural life has of course changed across the country due to the industrialisation and automation of agriculture, but I doubt that anywhere has the suburbanisation of the countryside advanced more deeply and rapidly in the past 40 years than here in south-mid Essex.
