(Benjamin) Laban Johnson was born 27 Dec 1859 at Stepney, baptised 19 Aug 1860 at Tower Hamlets. 1861, living with parents in Stepney. 1871, living with parents in Stepney. 1881, living with parents in Stepney. After that, no trace anywhere. No suitable deaths between 1881 and 1891. There is a Benjamin Johnson who died in Marylebone in 1897 aged 37, but where was he in 1891? Another possibility seemed to be d2Q1901, registered at Mile End Rd (Stepney) aged 40. The death certificate proved it wasn't him (and there was an error in the GRO as his age was 47 not 40).
