Historically in Lancashire, Kennessee Green grew when the Liverpool, Ormskirk and Preston Railway was founded. Wealthy families moved from Liverpool to the area and lived in the large Victorian houses around Tree View Court and Maghull railway station. By 1901, Kennessee Green was significantly larger than Maghull itself^{[citation needed]}, and was connected to Maghull through various narrow roads.

During the 20th century, Kennessee Green and Maghull both grew with housing estates being built which consequently connected the areas together. The new housing estates did not respect the historic street patterns of both of the villages. In 1974, Kennessee Green and Maghull were moved from the West Lancashire Rural District in the administrative and ceremonial county of Lancashire and placed into the newly formed Metropolitan Borough of Sefton in the also newly formed ceremonial county of Merseyside.

There are no signs to mark Kennessee Green as it is contiguous with Maghull.

Tree View Court includes a newsagent, a pharmacy, and a One Stop convenience store amongst other shops.
