William (29) and Ellen (26) Terry are in Bermondsey in 1851 with their children "Mariah" 5, John 3 and William 1, plus William's sister in law Eliza Goddard.
I wonder whether the enumerator made an error in copying over the entries into the summary schedule, inadvertently turning son Maurice into daughter Mariah?
