John Busby and Mary Ann (Jelliffe)

[Newbabe]

Can anyone help me find John and Mary Ann Busby in the 1871 census.  In 1861 they
are in Southwark and in 1881 they are living at 1 Field Place, civil parish Clerkenwell,
Parliamentry Borough of Finsbury, London.  John born Birmingham Warwickshire 1827
and Mary Ann Birmingham 1833.  Children Mary Ann born 1867, George 1865, and
John 1863 all in Clerkenwell, Middlesex.  Albert 1872 and James 1874 were also
born in Clerkenwell.  Other children who should possibly be with them are Harry Edward
1861 and Louisa Hannah 1859 both born Bermondsey, Surrey, William 1854 and Walter
1852 born Westminster.
The trascription of the name Busby on other census for this family and previous
generation have included Barly, Bushy and Bushby.
Any assistance would be very much appreciated.
