George and Jane are shown together in the 1871 census.
In 1861 Jane Brown was living with her mother Mary Brown at 3 Court, 95 Bishopsgate Street.
George Stokes is a visitor.  Mary was a widow.
The ages for Jane and George are consistent with later censuses.
Their first child, John, was born around 1863.

No suitable entries have been found on the IGI.
There is only suitable entry in the marriage index 1862 in Kings Norton registration district.

In 1862 Kings Norton had subdistricts of Balsall Heath, Edgbaston, Harborne, Kings Norton, Moseley, Selly Oak (Smethwick).
In the 1861 census Bishopsgate Street is in municipal ward of St Thomas and ecclesiastical parish of St Thomas.
However, Bishopsgate is not much more than half a mile from Edgbaston.
  

When Jane Louisa Stokes (9) was married her father is given as George Stokes, a polisher. Her residence is given as Birmingham.
Her birth seems certain.  Her father is given as George Stokes, gun polisher and the address of the mother is 2 Court, Stoke Street, Birmingham.
The family are together in the 1871 and 1881 censuses and George's occupations are consistent.
A definite marriage for George and Jane Bourne has not yet been identified.
The marriage certificate would be valuable corroboration of information.
The birth, early censuses and identity of his parents are based on finding the most likely entries.
Therefore the later identity of George is fairly certain, but the early identity less so.
  

From Baptism records it seems likely that this couple had other children.
They may have had a son called George baptised in 1862 who therefore must have died before 1874.
They may hav also had a son called Alfred baptised in 1867.
  

Apparently Died before 1891
There are two possible entries in the death index:
1886-Q4 Birmingham age 45  (born c. 1841)
1888-Q3 Birmingham age 49  (born c. 1839)

The latter corresponds better to his age.
There is a possible burial for the former at Warstone Lane Cemetery in 1886.
