According to the 1871 census, Harriet was born in Lincoln, so this is probably the marriage (from the LDS pilot site
http://search.labs.familysearch.org )
Henry HODGSON, son of Edward HODGSON married Harriet Elphir SHAW, daughter of Thomas SHAW at Lincoln on 28 May 1855. Groom aged 21; bride aged 19.
Harriet died just after the 1871 census:

Pancras 1b 6Did Henry marry Charlotte in Ireland? Several of their children were born there, and judging from the dates, they were probably still in Ireland when the 1881 census was taken.
A possible birth for Henry, also from the LDS pilot site:
Henry HODGSON, son of Edward HODGSON and Rebecca, b. 9 Jul 1836 and baptised 24 Jul 1836 at Sharon Independent, Tredegar Iron Works, Monmouthshire.
