William Knight
born April 1853–April 1854
  in Lydney, Gloucestershire
died very roughly 1923

1861 census: living with maternal grandparents and uncles and aunts at Hawkins Pill, Newnham. Age is 7 and place of birth is Lydney. Not certain that he is the son of Mary Sophia and Henry Knight, but seems highly probable (alternative interpretation is that one of Mary Sophia's sisters also married a Knight, but that seems unlikely).
