Joseph Craddock married Hannah Redman from Clerkenwell at St Andrew, Holborn in 1806. Their first child, Charles Tyrwhitt, was christened in 1809 at St James, Pentonville. Another son, Marmaduke Montagu Caracticus, was christened at St Dunstan in the West in 1817. The record shows his father as a silversmith and their address as Carey Street. Their daughter, Isabella Cecilia, was christened at the same church in 1821 from the same address. Her father said he was a goldsmith.
His wife, Hannah, died in 1830 aged 46 years. Her burial recorded at St George the Martyr, Queen Street shows her last address as Liberty of the Rolls. As a widower from St Pancras, he married Mary Boaz at St Mary, Islington in 1833. The burial in 1834 of a Joseph Cradock aged 53 years, late of St Pancras, was also recorded at St George the Martyr and is probably relevant.
