your very detailed presentation of the 1841 census is of interest
The 1851 census has 'my' moorhouse family at whitewell bottom mill. they still resided there in the 1871 census
also at shaw clough, whitewell bottom where the son jemes lived with his family.
there is a john moorhouse aged 51 on this census , a mechanic, born in burnley, living nearby at Lane Heard
The documentation I have on the mill says the acquired it in 1848
the baptism record for the 6 children in one go session on 5 july 1835 has their address as Sandy bank, newchurch in Rossendale
Sarah was baptised also in the chapelry of burnley on 16 july 1837 they then lived at Holt mill
both sandy bank and holt mill are on the road from rawtenstall to waterfoot and edgeside, on the main Bacup road.
The birth certificate for william enoch ( see 1861 census at whitewell bottom ) has the family address at that time as bridleway. This road links the main bacup road with Burnley road east, whitewell bottom.
interestingly the census for 1851 for whitewell bottom ( newchurch in rossendale) has a joseph moorhouse, weslyan minister, living at a Longholme place. he was 42
I hope this, from my notes of a few years ago is of interest
