There seem to have been some rearrangements in Islington Street over the years:
In 1921 the occupant of no. 4 is Oliver Pearson, licensed victualler.
In 1911 the occupant of nos. 2 and 4 is Oliver Pearson, publican, and John Lomax is at no. 6
In 1901 the occupant of no. 4 is John Lomax, the William and Alberta Pearson are at no. 6
In 1891 William Pearson 31 and Alberta are at no. 4 Islington Street
In 1881 nos. 1 and 3 Islington Street is the "Old Original Wagon and Horses" George Barker, coachman
at nos. 2 and 4 is William Pearson 49 Grocer and his family including William 21
In 1871 no. 2 Islington Street has William Harrison beerhouse and shop keeper
at no. 3 is William Pearson 39, cow keeper
In 1861 no. 3 Islington Street is Wagon and Horses, William Pearson 28 grocer and beer seller
In 1851 the street is simply Islington and there are no house numbers. I have not found a beerhouse, but I may have missed it: there are many households.
In 1841 there is apparently no such street which fits with the tithe map of 1838, where the area is undeveloped.
