A neighbouring Grade II* listed[2] barn has been dated to 1373, and as a result it is likely this was used to support the mill that stood on the site.

[4] Kingsbury Mill stood in land belonging to St Albans Abbey at the time of the dissolution of the monasteries across the country.

[5] The mill is again referred to 1568 when a "watermill and free fishery in St Michael's" were conveyed to Sir Nicholas Bacon by John and Frances Machell.

Following the death of Sir Nicholas and his eldest son Anthony, the Gorhambury Estate, and thus the mill, passed on to noted scientist and statesmen Francis Bacon.

Following Francis' death, the estate was bequeathed to Thomas Meautys who was married to Anne Bacon, the great granddaughter of Sir Nicholas.
