Is this them in 1901? Father Ernest a blacksmith (age 28 born Acton, Lancs), mother Evelyn?
RG13/3406/116/28
Living in Wallasy with father Samuel, sister Annie and a daughter, Mabel, aged 6 and a nephew Edward?
If so, then Ethel is not there which would lend a lot of weight to the story she died very young...sometime between 1893 and 1901 at least... If her sister was 2 then possibly about 1896-1898?
