I have now received from Sheffield Register Office the marriage certificate for William Henry ASHFORTH 1873-1926 and Florence ASHFORTH (née Florence FLOWERS 1876-1973).
William Henry ASHFORTH 1873-1926 and Florence ASHFORTH (née Florence FLOWERS 1876-1973) were married at the Church of Saint John the Baptist, Owlerton, Sheffield on the 25th of December 1895.
This really only confirms what I already know. Though it does verify William Henry's father as William Henry ASHFORTH 1851-1899.
