Why do you think a couple born in Somerset - they give Lopen as their birthplaces on the 1851 and 1861 censuses, married in Surrey?

(or Hillard)Somerset has very poor coverage of its parishes on the IGI. Less then 10% have any coverage, which means more marriages aren't on the IGI than are. Have you checked to see whether there is a marriage in Somerset for John Pook and Sarah, or do you know her maiden name was indeed Corbett?
Since Harriet's baptism was a non-conformist one pre 1837, the registers are held by The National Archives. This website has the images from the registers.
http://www.bmdregisters.co.uk/Often with non-confomist baptisms the mother's maiden name is given. Is this the source you have accessed to know Sarah's name was Corbett?
If not the Dorset and Somerset Family History Society hold a marriage index which would be worth requesting a search of
http://www.sdfhs.org/Sommarr.htmConsidering John and Sarah consistently give Lopen Somerset as their birthplace, regardless of whether they did indeed marry in Surrey or not, I think most further information about the family will be likely to be gleaned in Somerset, not Surrey.
