  This cant be Elizabeth, as Peter died 1789.  Also this Betty is of Deane, so would not be buried at Turton:
  Name:    Betty Mather
  Event Type:    Burial
  Burial Date:    25 Jul 1774
  Parish:    Turton, St Anne
  Reference Number:    GB127.L98/1/2/3
  Text:  "Betty Mather of Turton, Widow"
  
  I've read through the St Mary Dean burials and there is no Betty Mather, or wife of Peter Mather, or any other Mather of Little Hulton that died soon after these 2 children, so the Peter that married Ellen Howarth in 1762 must be another.
  
  If Betty survived Peter then she may have remarried Thomas Halliwell in 1792.  A Thomas of Farnworth died 1806, and Betty died 2 years later.  This appears to be a good fit.
