I'm sorry, carol80, but Thomas John Biddiss who married Catherine Butler Ray, was not the son of James John Biddiss and Elizabeth Berry.
By 1861 they had had 11 children: William Mar.qtr.1838, Mary Ann Mar.qtr.1840, Elizabeth Dec.qtr.1841, Sarah Ann Mar.qtr.1844, Jane Dec.qtr.1845 (d.1847), James Mar.qtr.1848 (d.1850), John James Jun.qtr.1850 (d.1853), Maria Jun.qtr.1852, Emma Jun.qtr.1854, Henry James Dec.qtr.1856, Eliza Mar.qtr.1861. Birth registrations on GRO confirm mmn Berry - no son Thomas John.
As Neale1961 has stated, in 1861 Thomas John Biddiss is living with his married sister Susan Bentley (she married husband Thomas in 1858 and stated her father as John Biddiss, Whipmaker, deceased. In 1851, in Newington, brother and sister are living with their remarried mother (married William Chuck 1846) and both have been listed as 'Chuck' rather than Biddiss. When TJ married Catherine he gave his father as John Thomas (deceased) but it should have been John William who died in 1845.
You refer to 2 Thomas John's born 1843 and 1845 with the latter being your man - however, there was only one Thomas John Biddiss and he was the one Jun.qtr.1843 Newington, mmn Boyd. His baptism shows he was born 25/4/1843, bp.24/12/1843 Newington and his sister Susannah Jane bp.9/3/1838 St Giles. (There was a brother John William b.1840, d.1841). In 1851 bc.1844 Newington, in 1861 bc.1843 Newington, 1871 (as Biddus) bc.1845 Newington, 1881 bc.1845 Lambeth, 1891 bc.1844 Walworth, 1901 as T J Biddigs (on FindMyPast) as bc.1844 Newington. So he seems to have got confused with his ca.birth year and place but all the census sightings I've listed are for the same man. Can't find him in 1911 but perhaps in workhouse.
John William Biddiss was bp.14/4/1811 Southwark, son of John and Mary. This takes us back to John Biddiss and Mary Askew i.e. John William and James John being brothers. You'd just credited Thomas John to the wrong brother.

Thomas John and Susannah Jane are children of John William Biddiss (Whip maker) and Susannah Boyd who married 1835.
