I have posted off an order for the following certificates to Sheffield Register Office:

Birth Certificate: Alice TURNER 1862-Deceased
Marriage Certificate: George FLOWERS 1839-1891 and Harriet FLOWERS (née Harriet LAW 1836-1903)
Marriage Certificate: George ELLIS 1860-Deceased and Emily ELLIS (née Emily ROSEWARNE 1865-1944)

Hopefully this will provide the information I need to extend my research of these lines.
