The Rise and Fall of Infamous Serial Killer Mary Ann Cotton 

Upon William’s passing, Mary Ann was entitled to a windfall of £35 from his employer-provided life insurance, benefiting both her and her children. This sum, equivalent to today’s £3,371, mirrors the earnings of a manual laborer over six months during that period, marking a significant financial uplift for the family.

Mary Ann, newly affluent from her late husband’s life insurance, relocated to Seaham Harbor. There, she became entangled with Joseph Nattrass, initiating a deep relationship despite his existing engagement. This encounter marked a new chapter in her life, weaving complex personal ties.
