Following the 1841 walk on the NLS 1840s map, he starts in Seneley Green (which takes over 5 pages), deals with the houses in Strange Lane, then backtracks to Seneley Green. The schoolmistress is a couple of doors before Strange Lane, and I would expect her to be close to the school. School Lane is not listed by name, but seems to have no houses in the 1840s..
Hattons Yard is then listed, then Gibbons Lane. The route then follows the northern side of the district, ending at Leyland Green. I have to assume that the route took in all the buildings in that area.
Tithe Barn Lane and Tithe Barn Hillock, to the south, are in another enumeration district, so that is not the route.
The only two groups of buildings which might be described as a "yard" is marked as "Crow Trees" on the 1840s map (by the 1890s it is called "Manor House") and Seneley Green Stables.
THEN
I looked at 1851. Henry Sutton, age 45, was at "Hatton's Fold". It has to be the same man. The enumerator's walk then goes from Ashton Cross, along Tithe Barn Lane and then Arch Lane as far as the parish boundary. Presumably backtracking to Tithe Barn Hillock, the man then visits Penny's Lodge, where the gamekeeper lives, before reaching Hatton's Fold. There are four households, then Seneley Green is reached. The front page says "to and including Tithe Barn Lane, Hatton's or Tunstall's Fold, Tithe Barn Hillock, Arch Lane..."
In 1861, Henry Sutton is down as being at "Dunstall's Fold", between Tithe Barn Hillock and Arch Lane. Tellingly, George Greenall is still next-door-but-one.
My guess is that the Fold was pretty close to what is now Tithe Barn Farm.
In 1861, the route goes from Ashton Cross, along Tithe Barn Lane and then Dunstall's Fold. It then follows Arch Lane, then "Penny Hall", where the gamekeeper lives, then "Torpen Howe", which is shown on the map, north east of the end of Arch Lane. The enumerator then follows the track east to Seneley Green. The page at the front of the ED says "Tithe Barn Lane, including Dunstall's fold, Tithe Barn Hillock.."
