I've gone back through the certificates that I have.
George Hudson Bowley was listed as a "Driver" for the Royal Artillery based at Woolwich Barracks at the time of his marriage in 1867.He is at the same location in 1861 on the census, shown as a "Private".
If you can view the 1861 census return for George Bowley you will see that his age is given as 14 on the transcript.However if you view the document itself you will just about see the two loops that make the "1" into a "2" thus making him 24(B.1837).His place of birth is also given as Paddington.
I am very comfortable with the information that I have and believe that transcription/information given to the enumerator is the problem.In 1881/1891 there is a mix up between where his wife (Sarah Ann Taylor) and latest husband (George Collins) are born - one says St Pancras (London) the other Birch Green in Hertfordshire - they are reversed in the later census.
I have tried just about every variation on the name of Bowley to try and get a hit for the 1841 and 1851 censuses.Unfortunately it has been without success.There is a close match for a Richard Bowley in 1851, with the roughly the right age, showing as a servant in Sussex but no family attached to him.Unless he too is a soldier and posted overseas somewhere?However I would have expected to find him on at least one of the two censuses.
