Browsing the England and Wales Census 1841 I came across the household of Joseph and Ann LAW living at Trippet Lane, Sheffield, Yorkshire.
Joseph is 24 years of age and Ann 20. These may have been rounded down, though since Joseph's age is given as 24, I am not so sure.
Two children are recorded: Harriet LAW age 4 years and Joseph LAW age 7 months. Daughter Harriet's age is exactly as expected so perhaps I should pursue this line of research further.
Hopefully I can find a marriage for Joseph and Ann LAW and establish Ann's maiden name.
