In 1871 there is a very badly transcribed family, I suspect the page must be damaged or something.
ED: 4
Household schedule number: 36
Roll: CSSCT1871_97
the address appears to be Greenock Middle, Renfrewshire
Ch?? 36 Labourer born Amegh, Ireland
Ch?? 32 born Amegh, Ireland
Ch?? son Labourer born Anburn, Ireland
Ch?? 13 son Labourer born Anburn, Ireland
Arthur 11 son Anburn, Ireland
?? Ann ?? daughter 10 Greenock
John Ch?? daughter 5 Greenock
Jane Ch?? 3 daughter 3 Greenock
there seems to be another family in the household too, maybe called Forman.
I just picked on this family because of the coincidence of the name Arthur and possibly others and birthplace of Ireland, but it may well show that there are problems with the documents for the area for the 1871 census.
I don't use SP so can only give you the references, which should be standard but I can't guarantee it.
