At long last I seem to have found a maiden surname for the spouse of William Henry ASHFORTH 1851-1899. I have received from Sheffield Register Office the birth certificate for Rosa ASHFORTH 1874-Deceased.

Rosa ASHFORTH 1874-Deceased was born on the 23rd of February, 1874 at 83 Duncombe Street, Nether Hallam, Sheffield, Yorkshire, England. Her father is William Henry ASHFORTH 1851-1899 and her mother Ellen TOMLINSON 1855-1943.

My notes show I have a baptism record for Rosa ASHFORTH 1874-Deceased:

Ashforth, Rosie (adult) (of 172 Cuthbert Bank Rd).
Baptised December 5, 1888, by AH Rhodes at St John the Baptist Church, Owlerton.
Parents name(s) are Helena; William (File-cutter).

Rosa ASHFORTH 1874-Deceased is recorded as an adult. It would appear both William Henry ASHFORTH 1873-1926 and Rosa ASHFORTH 1874-Deceased were born before their parents were married.

This probably explains why Rosa was nearly 15 years of age when she was baptised.

My notes show a marriage in 1876 for William Henry ASHFORTH 1851-1899 and Ellen TOMLINSON 1855-1943. I will submit a request to Sheffield Register Office for this marriage certificate.

Notes:
The Church of Saint John the Baptist, Owlerton, Sheffield, Yorkshire, England.
