As far as Catherine is concerned I don't think she married. She appears by the census records to have been a servant all her life in various locations.
Her MI from Andreas Old Yard gives:
Z 13 In memory of / ELLEN JANE RADCLIFFE, / who died Dec. 10th 1866 / Aged 22 years. / "My flesh also shall / rest in hope". / Also / CATHERINE RADCLIFFE, / died June 18th 1913 / Aged 78 years.
