Event(s):
Birth: 
Christening:  22 MAR 1812   Saint Peter, Bolton Le Moors, Lancashire.
Parents:
  Father:  HY. FAIRHURST
  Mother:  BETTY 

Baptism record reads:
Mary d of Henry and Betty Fairhurst of LB
22 March 1812

Died after 1861

Possible Death, but not on 1871 census (but neither was Isaac) !
Deaths Sep 1871   (>99%)
Mather  Mary  58  Bolton  8c 251

Deaths Sep 1882   (>99%)
Mather  Mary  69  Bolton  8c 218

Deaths Dec 1883   (97%)
MATHER  Mary  72  Bolton  8c 245

Deaths Jun 1882 (born Turton)
MATHER  Mary  78  Farnworth (Workhouse)


There was a Mary Mather in the same workhouse as Isaac in 1881, and died in Bolton in June 1882, but was recorded as from Turton, born 1805, which conflicts with census records.

Mary Mather is buried in a common burial at Tonge in a grave with 13 others, all buried between 4-16th October 1871.  She is the only Mather, and grave Ref: CATHOL-3RD/G/95 suggests Catholic, so possibly the wrong person (or simply non-conformist, not CoE).
