There do seem to be quite a lot of John Postlethwaites and the one with Elizabeth was born in ulverston in Lancashire, not Cumberland which is separated from ulverston by Westmorland.

1861 John and Elizabeth (and Edwin J) Occ:  Prison Officer Still looking for a marriage between them

Could this this birth relevant?
Dec 1861 Clerkenwell 1b 528
Postlethwaite, William John
mother Page

Elizabeth was 29 in the 1861 census, born Gedney Hill, Lincolnshire
A baptism at Gedney Hill, 24 April 1831
Elizabeth Page (common name!)
Parents Stephen and Mary

She is there in the 1841 census, don't know about her after.

I thought maybe both Elizabeth and WJ had died in the mid 1860's and both buried Victoria Park Cemetery, but now I am not so sure, their ages were out (especially young WJ)

There is a William John Postlethwaite born London circa 1862 about in Cumberland later (as per 1891, 1911)
Married Sarah Boak in 1886, Whitehaven, by the looks of it
But in 1901 says he was born Maryport Cumberland!

In 1851, Mary Roberts Postlethwaite is born London.
The 1871 which Rosie found is b Cumberland.

So did he have wife Mary Ann, then Elizabeth, then Mary

Birthplace Frizington! Do they mean residence?

[heywood]

There is this man in 1861 who I think may be the one from 1871

1861 324 / 29/2
10 New Western Street Bermondsey

John Postlethwaite widower 45 yrs Manager Wine and Beer Merchant b Ulverston
William Kirkby Postlethwaite 12 yrs b Liverpool

Added
Just realised John is with Elizabeth in 1861 so maybe this is just another one 

Perhaps he is the one who dies in 1875.

I think this is the one Rosie found - his occupation looks like ‘Wine... Commission Agent’ - dreadful writing so he can be discounted for 1871.

The burial is 1860, Jon .

Another burial for Elizabeth Postlethwaite, 38 yrs , 16 September 1866 , 45 Red Lion Street, Clerkenwell in the  same records.

There is also the child William John in 1865

It may be that these are all the same family but then you have the adult William John
  confusing.
