I am trying to find details about Mary Clegg my 2nd great grandmother.
She was baptised 20 Aug 1819 at Manchester Cathedral, father James Clegg, mother Ann.
She Married 22 Aug 1839 to John Kennedy at Manchester Cathedral
John Kennedy died 4Q 1853
She remarried 5 Nov 1855 to William Henry Hartley at St Phillips, Manchester
Her last known address was 8 Clayton Street in Manchester (1881 census) where she resided with her son in law Michael Spencer and daughter Elizabeth Alice.
She is in the 1881 census but not the 1891 census, died between 1881 and 1891?
I have checked the UK Registry Office and found 50 Mary Hartley's registered deaths around Manchester between 1881 and 1891. On checking for registrations near Ancoats there were 5 in Chorlton and 1 in Salford (excluded).
I would like help on advising where to search next for details of her death?
