As a pilot for the 1881 census, the LDS indexed the 1851 census for Devon, Norfolk and Warwickshire, and they have issued the data as a CD. While it does not cover Hertfordshire it can be searched for people born in Hertfordshire (as HRT) living in one of the indexed counties. However you should realise that the spelling of Hertfordshire place names is erratic and, for example, there were people living in Exeter, Devon from "Bishop Stafford", "Bishops Stortford", "Bps Stortford" and "Bishops Storiford."
