Dear Glenpanny and Fedelmar ...
Was fascinated by the topic so I though I'd have a quick look at the SEAX site at the ERO. This specific document came up which relates directly to the mill at the time you are looking at:
D/F 35/1/4
Dates of Creation 1803-1804
Scope and Content Valuer's notebook
Hardings and Repentance Farms, Greenstead and Bobbingworth, including crop details, 1800-1804; property belonging to Peter Harris, miller, Takeley including STEBBING MILL and House, including farming stock and watermill stock;
Date From 1803
Date To 1804
There is also a tith map dated circa 1830 which is stated to include drawing of the TWO mills at Stebbing. So, worth a visit to the ERO/SEAX website !
The plot thickens !!
Aye
