Ann and sister Mary were twins, dughteers of James Mather a farmer.
In 1841, there are no Ann and Mary Mather twins on the census, and no deaths for either registered in Bolton.
Ann Mather fits the profile of the Turton Mather family with connections to Sharples, Turton Bottoms, Astley Bridge and Walmsley. However there are no DNA matches to the 4 tree owners (Oct-2020) and Ann was born Bolton (i.e. not Shaples or Turton).
20 Nov 1858, Ann, daughter of James Mather, a farmer, married James Mason, a widower, at St George's Little Bolton (this cannot be Mary Ann Mather, aged 14 in 1851)
8 Mar 1910, Ann Mason died at Bottom, Sharples.
