Hi PopT - just using various resources, an Eric W. Glossop is shown in the "Ecclesall B." births index in Jan-Mar 1924, his mother's maiden name being given as Leonard. A William Glossop married a Mabel I. Leonard in the Ecclesall district in Apr-Jun 1919.
At 35 Thorpe House Road the 1942 Kelly's Directory shows "Edward Ward, police constable", but at 37
Thorpe House Avenue
is "William Glossop, registrar".
I couldn't find a death entry for an Eric Glossop, so perhaps he survived the crash?
Hope this is helpful!.
