A Corn Mill was first recorded at Okenthorpe (later Jowett House) in the 13th century. A new mill building was constructed in 1707 and this was later replaced by another in 1803 which largely remains. The building was converted to a saw mill by 1903, possibly in around 1854 when a new wheel was put in. The mill converted to electric power in 1963 and the site is now a residence. (Umpleby 2000, 90-93). There are possible remains or earlier mill structures within the current site (Harratt 1998, 6.1) giving fragmentary legibility of the former mill.
