Death sought for couple William Kane x Bridget O'Neil

[NicolaasMars]

I have been unable to find the death of the couple
William Kane (also Cain, Kean), bapt. RC 24-11-1823 in Newry, Co. Down, and
Bridget O'Neil (also O'Neal), bapt. RC 11-05-1829 Armagh, Co. Armagh.
They married on 18-10-1844 in Newry, Co. Down.
The couple had seven children, as follows:
Anne, bapt. RC 14-02-1847 Clonallen, Do. Down
Anne, bapt. RC 01-01-1849 Clonallen, Co. Down
Thomas, bapt. RC 27-07-1850 Clonallen, Do. Down
James, bapt. RC 25-06-1854 Liverpool (St Patrick)
Rose Ann, bapt. RC 13-04-1856 Liverpool (St Patrick)
John, bapt. RC 03-05-1858 Clonallen, Do. Down
Alice, born 24-01-1861 West Derby, Lancashire.

I find the couple, as lodgers, without children, in the 1851 census in Toxteth Park, West Derby, Liverpool. William is carpenter.
I find the couple, with five children, in the 1861 census in 35 Fisher Street, Toxteth Park, West Derby, Liverpool. William is ship joiner.
In the 1871 census, I find at 29 Fisher Street, Toxteth Park, West Derby, Liverpool, mother Bridget with the children James, Rose Ann, John and Alice.
In the original census form, the word "wife" is crossed out after Bridget Cain's name. No mention is made of her husband (nor of her being a widow).
I do not find William in 1871 or later.

I have been unable to find death dates that fit these data for William and Bridget. Any help will be highly appreciated. (I searched in ancestry, FindMyPast and rootsireland.ie, without success.)

Nicolaas -- there is a dataset on Ancestry for RC burials in Liverpool. (Just go to Card Catalogue and input Liverpool Burials - one option you will see is for Roman Catholic Burials).

However there doesn't seem to be a burial recorded for William Cain (or variant). As he was a Ship's Joiner - he may have died away from home.

(There is an RC burial for a Bridget Cain, aged 50 and of 10c Worthington St, at the Ford Cemetery on 24 Oct 1877 -- or have you found Bridget after that date?

Thank you for pointing me to this useful database on Ancestry! I was not aware of it.
The Bridget Cain you found is a likely candidate; I have now applied for her GRO death record.

Her husband, the ship joiner, is still at large...

In the same database I found the burial of William! He was buried in St Oswald cemetery in Liverpool
on 13 April 1863, aged 42, under the name Gulielmus Kain. The address given, Fisher Street, agrees withthe 1861 census entry.

Oh well done Nicolaas!! I am so pleased that you found him (and hanging my head in shame that I didn't!!)
