Bairne-Witemburg-Hannover

From the census records of 1860-1880 I have seen these places listed

as my GGgrandfathers place of birth. BAIRNE-WIRTEMBURG-HANNOVER.
Are these places one and the same in the former Kingdom of Hannover?
I have been trying to trace down exactly where he was born. Can anyone
help me with this?

Hallo Phyllis!
Its possibly, that Wirtemburg was perhaps "Wittenburg", a small village 15km
in the west of Hildesheim, which was still 1866 a part of the kingdom of
Hanover.
