Hi there Michelle
According to the Junes Barnes 1851 Census transcription; the information you want is as follows:
HO107/ 1643/ Folio 746/ Page 88 – Newhaven.
HENTY Phillip, Head, Marr, 39, Ag Lab, born Chalvington, Sussex ?
Elizabeth, Wi, Marr, 50, Piddinghoe, Sussex.
Edward, Son, Unm, 20, Ag Lab, born Piddinghoe.
Phillip, Son, Unm, 17, born Piddinghoe.
Wiliam, Son, Unm, Shipwrights Appr, born Piddinghoe
Have not got an exact address, Folio 743 and 744 are Blue Anchor, 745 is Ship Inn, but all we have for 746 is Newhaven Village.
Hope that aids your research
