I have a birth certificate for 1874 showing place of birth as Marmon Place, Helynge Street, Aston. But when I try to find that place on the 1871 census I keep drawing a blank. The nearest I can get is Heneage Street, Aston. Are they the same locations and the certificate has a transcription error. Even then I can't find a record of Marmon Place. Can anyone help?
