I suspect that Daniel Kneen and Lucy Christian had a son Daniel 1805 in Bride who married a Margery Bradshaw in Manchester who had a daughter called Lucy in Runcorn 1844 who married a Thomas Corkill and had a daughter called Jane 1874. Jane is 27 in the 1901 census.

See 1881 census on line for both the Corkills and Millsons.

Harold Millson is seen with his family in Wirral. Both parents, I think, are dead by now. They appear to be Elizabeth (Lamb?) and William Henry Millson .

Sarah Hamy shown with the Millson family is probably Sarah Harvey.

As Sue suggests start with the marriage certificate and see what fits.
