The 27 Oct 1841 burial may be wrong record for two reasons: Betty was a widow, so not "Wife of John Mather", and the age at death should be about 75, not 64. However, there is no other death record that matchyes a Betty of Elizabeth aged 75 in 1841.
There are other John and Betty marriages 1790-1810 in Wigan (Betty Baxter & Houghton), Blackburn (Betty Walmsley), Bury (Betty Bentley), Leigh (Betty Ingham), Walmersley (Betty Bentley) that could be this death.
