Hi Claire,
Was interesting to see you post about number 22 High Park, as my family ended up there as well (sometime around 1910 / 1920), and that address appears on a number of my familys marriage certs.
The houses were back to back, so there was likely two families living at number 22.
One thing I have noticed is families seemed to jump about the house numbers between census, not sure why that is.
There are some photos of High Park Street on here, I will try and find them if no ones gets there before me
I couldnt find a census for 1871 for some reason, but William and Elizabeth Cook must have moved on by 1881 as there are not shown in High Park Street.
In 1881, there is a family at Nunber 20: Henry Cook (72), Mary Cook (66), Samuel Cook (29), Ann Cook (45), John Cook (36), Henry Cook (9), Victor Cook (2) and Lilly Cook (2).
In 1891, its possible Henry and Mary had passed, and some of the family had moved on, as Number 20 has the following living there: John Cook (46), Hannah Cook (49), Henry Cook (19), Victor Cook (11) and Lilly Cook (11)
By 1901, the only cooks in the steet are,
Back of No 7: Samuel Cook (26), Annie Cook (23), Samuel Cook (3) and Harry Cook (9 months)
Swans Buildings, High Park Street: John Cook (20) and Emily Cook (19)
