While a history summary of 1994 indicates that Shepperton meant Shepherd's habitation, which would earlier have transliterated into late Saxon language as Sceapheard-ton, the place has been found in "a document of 959 AD" as Scepertune, which the book "Middlesex" (Robbins, 1953), states instead meant Shepherd's farm. The name of one of the older lanes, Sheep Walk, may date to the medieval period and was perhaps on a wide tract of low-lying meadows which produced the Middlesex wool, namely marsh wool, which was included in a valuation of 1343. The valuation was two years after Edward III imposed wool tax — Middlesex rendered a sack for every s of the county (contributing in total 236 sacks) – much of which however appears from contemporary returns to have been collected from other riversides in the county including, in particular, Hampton (which includes Hampton Court).
