Have you any idea when / where she might have been born? There's a Winifred A born 1896 with parents George and Mary Ann, in 1901 and 1911. She's a dressmaker, and seems to have married in 1923 a William Williamson, in Ealing. But that Winifred may have been the one who died in Somerset? Is that any help at all? even by eliminating her?
