When William was about four years old the family moved to Thorpe-le-Soken, Essex. His father died of cholera in London in 1827, when William was ten years old, and was buried at Thorpe-le-Soken. After her husband's death, Elizabeth Gull devoted herself to her children's upbringing on very slender means. She was a woman of character, instilling in her children the proverb "whatever is worth doing is worth doing well." William Gull often said that his real education had been given him by his mother. Elizabeth Gull was devoutly religious—on Fridays the children had fish and rice pudding for dinner; during Lent she wore black, and the Saints' days were carefully observed.
