SMITH, Hoddesdon area, Early 19th century
You don't provide any sources but I guess
you have James Smith's place of birth from
one or more census return from 1851 on, and his father's name and occupation
from James' marriage certificate. You also
don't gives the names of any of James' children - while the page
The Inheritance of Single Christian
Names indicates that this can provide an important clue.
However I suspect your difficulty relate to either (a) your lack of knowledge of Hertfordshire geography and neighbouring parishes (b) taking census ages too precisely - particularly in families where members were likely to be illiterate, or (3) assuming that because the surname was Smith it must be particularly difficult - have a look at the topic "Right Name, Wrong Body" and you will see that in a given locality even very uncommon surnames can sometimes cause problems.
On getting your message I decided to search the 1841 census for Hertfordshire, using Ancestry, looking for a George Smith of a vaguely suitable age. There were 21 - and only one of these was close to Hoddesdon. On looking at the page image I found that the following household had been living at Flamstead End, Cheshunt:
Familysearch shows this James to have been baptised at Broxbourne on 17th October 1824, with George and John Smith baptised 16th November 1828 (what happened to John?) and Charlotte christened 10th of November 1833. The best fit marriage is the George Smith who married Sarah Moss at Wormley and if this is the right George there were possibly older children.- perhaps baptised in Wormley.
A quick spot check shows that James, George and Charlotte all gave a birthplace of Hoddesdon in the 1861 census, assuming my identifications are correct.
If you can add to the information given above tell me.
