There isnt a birth registered for MATHER+LEE (Except Sarah J Mather, Edgworth, 1856). That is because Elizabeth was born (and the birth registered Q4/1853) before they were married.
Elizabeth was baptised 25 May 1855 when Richard was a Carder in Little Bolton (probably Harwood).
In 1861, she was known as Elizabeth Mather which must have been confusing as there was her cousin (and perhaps adopted sister), Elizabeth Mather, Robert Mather's daughter.
Elizabeth's mother Betsy died in 1861, and father Richard 5 years later, so in 1866 Elizabeth, aged 13, probably went into service.
After 1871, it is not obvious what happened to Elizabeth. She didit die. Sha may have married John Rice in 1867 but not Robert Roberts in 1870.
