Perhaps Sarah Cluney who died 1927 is the second wife of Thomas Cluney (Sarah's dad)
As on Can 1871 family listed as follows
Thomas Cluney 56 (b 1815 Ireland)
Bridget Cluney 50 (b 1821 NS)
Children
Sarah 22 (1849)
Thomas 21 (1850)
James 19 (1852)
John 18 (1853)
Mary 15 (1856)
Edward 12 (1859)
David 10 (1861)
Elinor 9 (1862)
Elizabeth 7 (1864)
Hector 4 (1867)
William 3 (1868)
Finley 2 (1869) (iligitamate son of Sarah 1849) as on 1881 he is then Finlay Dawson the surname of Sarah and my George Dawson who married in 1875.
A Bridget Cluney died 1900 in Halifax, just checked it on that site
Says she was 59 and single so perhaps she is a daughter of Thomas and Bridget the mystery depens.
The marriage of Thomas Cluney (aged 26) and Sarah Kate Bennett in 1875 must be Thomas son of Thomas and Bridget and the brother of Sarah (1849)
So I think the death as shown for a Sarah Cluney in 1927 is most likely the second wife of Thomas Cluney previously married to Bridget.
and therefore still need to find the death of Sarah (Cluney) Dawson b 1849. If it is in 1923 then she must have divorced George Dawson as he is not with Sarah after 1882 as thats when he remarried.
So her death maybe recorded as either Sarah Cluney or Sarah Dawson depending on whether she resorted to her maiden name or not.
