There is a Mr R. Richards, born 19.9.93, and a Mrs Richards, born 11.2.16, of 34 Heastley Rd Nottingham, travelling on the "Stirling Castle" from Southampton to South Africa, departing on 17 Feb 1955.
For some reason, the entry for Mr R. Richards has been changed by hand (the entries are typewritten) to read Mrs. R. Richards, but it looks like this could be them?
