Hi Dave,
Would be grateful if you could look it up.
I am differing with you on John Cockroft being at Illignworth Moor area 1841 . I still think it might be Broad Street, Halifax but leaving open mind on that.
I have looked at all William Smith and wife Ann on 1851 to find only one that might fit, if they are still alive and that is
at Temperance Street district 11.
Hannah Smith 53 wife howarth
William Smith 55 m head warley
Harley Smith 9 son ov
Henry Smith 27 m head ov ?
Joseph Smith 23 un son Heptonstall .
They could be on the 1841 and Christopher might be with them, if they are the right ones.
