Milton Keynes
Within Milton Keynes is Milton Keynes Village, the original village that was built around to create the New Town.
The Saxons originally named it.
In 1067 after the Norman conquest it appears in the Doomsday Book, as Middletone, the Old English for 'middle farmstead.’ Meaning it was the middle one of three settlements or farmsteads, the other two almost certainly being Broctone (later Broughton) and Waltone (later Walton)
Post Norman conquest, the villages feudal masters were the de Cahaignes, (pronounced de Kaynes) who also held Ashton Keynes, Somerford Keynes, and Horsted Keynes (modern spellings)
By the 13th century the village had been anglicized to and was known as Mideltone Kaynes.
Everyone called Keynes descends somewhere from the de Caignes later spelt Kaynes, then Keynes.
John Milton has no connection, other than that the name Milton also evolves from the Old English word Middletone for farmstead, and later Mill town.
The name Midleton Kaynes slowly evolved into Milton Keynes over the centuries.
In 14th, 15th centuries, the estate was owned by the Stafford family (have coat of arms) who sold out in 1658 to Heneage and Daniel Finch (father and son who lived in Rutland- also coat of arms) Other landowner is CofE but rectors appointed by Lord of the manor.
1939 last male member of that part of the Finch family dies and it's sold to William Mitchell, (rich but not gentry AFAIK) then towards end of WW2 sold to the Society of Merchant Venturers of Bristol. The Society had bought up several local estate villages and their estate office was in Milton Keynes Village. Society then sold to the Milton Keynes Development Corporation.
However during planning, the decision to name the City after the village it was built around, was announced to Dick Crossman, housing minister in Harold Wilson's late 1960’s cabinet.
It's claimed Crossman was looking at the map of the area where the town was going to be built around MK village when told, and commented: "Milton the poet, Keynes the economic one. 'Planning with economic sense and idealism, a very good name for it.'" The press repeated it and that is where the naming myth came from.
(Quite a few of the planners and their friends took advantage of villagers 'evacuating' and selling up when the plans went through, to buy up housing in the village and modernize it, thus changing the 'social level' of who lived in the village and it's nature.)
