Hi
Could it be Lock Hill rather than Loch?
There seems to be a Lock Hill in Killamarsh - hard to pin down on a map but if you Google it someone claims to have lived "at the bottom of lock hill in Barracks yard ( 12 Nethermoor Lane to be exact)".
Nethermoor Lane runs from Sheffield Rd to Ashley Lane, though they don't seem to join. See
www.streetmap.co.uk/mapYou can also see Ashley Lane at
www.old-maps.co.uk and if you find where Nether Moor is marked, just below Belk Lane (now called Sheffield Rd I think) there is a Lock marked on the canal I guess. That is an 1892 map so a bit older than what you want but it might give you an idea of the place.
Google maps is worth a go too because you can look back and forth between the satellite and the map view. You can put in that 12 Nethermoor Lane address and see where it is.
