Ada Chard Williams (1875–1900) was a baby farmer who was convicted of strangling to death 21-month-old Selina Ellen Jones in Barnes in London in September 1899. Florence Jones, a young unmarried mother, had read an advert in the local newspaper which offered to find homes for unwanted children. She agreed to pay £5 to a Mrs Hewetson (Ada Chard Williams) but could only give her £3 on the day. She returned later with the balance and found that Mrs Hewetson and Selina had vanished. She was suspected of killing other children although no proceedings were brought.
